This is my first time posting outside of sage-support, and I'm not sure if I should be posting here or in sage-devel. Anyway...
When building sage-4.7.2.rc0 in Ubuntu 11.10, I receive the the following message:
configure: error: --with-readline=yes (default) and headers/libs are not available
Error configuring R.
The readline spkg seems to have installed correctly, according to readline-6.1.log: "Successfully installed readline-6.1". I've attached a compressed tar file containing readline-6.1.log, along with install.log in its entirety.
After some googling, I see I'm not the first to encounter this problem. However, for others the error disappeared after installing readline-common and libreadline6-dev, which I already have installed.
Any advice? Please let me know if I should provide additional information.

Yes, we're aware of that, although it apparently doesn't happen on all
Oneiric installations.

John Hoebing reported on sage-release that UNinstalling libreadline-dev
solved the problem for him; it should be safe (and IMHO work) to
reinstall the system's libreadline-dev *after* you've built Sage /
installed its R package (in case uninstalling solved the issue for you).
The problem is that Ubuntu changed its libraries; libtermcap used to be
a dummy library with its symbols included in libncurses, but that's no
longer the case, apparently at least if libreadline-dev is installed.
(And while Sage ships and builds a *static* libncurses [for some other
packages], its libreadline doesn't refer to the other necessary
libraries. Furthermore, the R we ship isn't aware of that change, i.e.,
its 'configure' just tries to link the failing test program to
libreadline and libncurses.) It seems the missing symbols are now in
libtinfo on Ubuntu, located in /lib/, as a replacement for libtermcap.
As an alternative, using the system's libreadline instead of Sage's
should also work. You'd have to create symbolic links to it in
$SAGE_ROOT/local/lib/, or *copy* your system's libraries there (before
building R, or before building Sage and first 'touch'ing
$SAGE_ROOT/spkg/installed/readline-6.1 to make Sage believe its readline
was already installed).
Unfortunately there are various ways to fix this, none of them very easy
or "straightforward". You *might* also try to install the new readline
6.2 spkg [1] from #11882 [2] which isn't included in Sage 4.7.2,
although I'm not sure (or rather doubt) that this solves the problem.

P.S. (to the other readers):
There's a restructured R 2.10.1.p5 spkg awaiting review since quite a
while; any change to (or upgrade of) the R spkg should be based on that.
I also have a not yet finished p6 based on the former; see #9906 [3]
and #9668.

FWIW, perhaps the easiest solution is to just create symbolic links in
$SAGE_ROOT/local/lib/ to the system's "unbroken" libncurses, i.e., you
should try the following:
$ cd $SAGE_ROOT/local/lib/
$ ln -svf /lib/libncurses.so.5
$ ln -svf libncurses.so.5 libncurses.so
Then go back into the root directory of the Sage installation and resume
the build (which should start by attempting to build / install R again):
$ cd $SAGE_ROOT
$ make
(Replace $SAGE_ROOT in the above commands by your actual directory,
which according to your logs is '/opt/sw/sage/4.7.2-rc0/'.)

I will try this now and let you know how it goes. Thanks for the
clarification.

If this doesn't work, the most interesting logfile is
$SAGE_ROOT/spkg/build/r-2.10.1.p4/src/config.log btw. (in case R's
'configure' again fails).

Sorry for the late reply, leif. I cannot tell you if your recommended
solutions work or not, as now I am encountering a different problem:
ATLAS is failing to build. (Actually, ATLAS usually failed to build
while I was having the readline problem. It only succeeded once or
twice to let me get far enough to see the readline error in the first
place.)
I get an error about an illegal instruction. Some more Googleing
revealed that when this occurs, the system is usually under high load or
has dynamic CPU frequency throttling enabled. In my case, the only
significant system load is the Sage build process (as revealed by the
top command), and I disabled CPU throttling at the BIOS level. I also
disabled CPU throttling at the OS level just to be sure, via the command
`sudo update-rc.d ondemand disable'.
I've also seen it suggested that I simply try running `make' again.
After a dozen attempts, this has not worked for me. Also, the `sensors'
command says the laptop is only ~70C while building, so I doubt it's a
temperature issue.
I wish I knew how ATLAS managed to build those two other times. Even
more so, I wish I could make it build now. :)
Here's a snippet of the error. Full logs are attached. For the record,
my CPU is an Intel Core i7-620M. Also, this error occurs with
sage-4.7.2.rc0 AND sage-4.7.2.rc1.

Well, it's system(ln) (some string variable, "line" I guess), not
system("ln"), which wouldn't make sense btw.
@Michael:
Did you try setting SAGE_ATLAS_ARCH?
(See
http://sagemath.org/doc/installation/source.html#environment-variables
-- oops, that's still the 4.7.1 documentation; see e.g.
http://sage.math.washington.edu/home/leif/Sage/tmp/installation/source.html#environment-variables
instead.)
In your case, indeed
$ export SAGE_ATLAS_ARCH=Corei7,SSE3,SSE2,SSE1
might work. If not, try some more generic setting, e.g. "Core2" instead
of "Corei7".
But "illegal instruction" is very bad at that point. This could be an
ATLAS bug, a GCC bug, or even due to defective memory, an overheated CPU
or whatsoever. If you always get the *same* error (at that point), it's
likely to be just a bug.
Btw., 70� C is quite high, although I don't have your processor's specs
right now.
At least for ATLAS, you might also unset MAKE (i.e., not use "-j") and /
or SAGE_PARALLEL_SPKG_BUILD, in case you haven't already.

Actually, it's
int GetL1CacheSize(int MaxL1Size)
{
FILE *L1f;
char ln[80];
int L1Size;
if (!FileExists("res/L1CacheSize"))
{
sprintf(ln, "make RunL1 MaxL1=%d\n",MaxL1Size);
assert(system(ln) == 0);
}
L1f = fopen("res/L1CacheSize", "r");
assert(L1f != NULL);
fscanf(L1f, "%d", &L1Size);
fclose(L1f);
fprintf(stderr, "\n Read in L1 Cache size as = %dKB.\n",L1Size);
return(L1Size);

Hi leif,
After fiddling with SAGE_ATLAS_ARCH, ATLAS build fine, and I encountered
the libreadline/R error as expected. After following your instructions
---
cd $SAGE_ROOT
ln -svf /lib/libreadline.so.6
ln -svf libreadline.so.6 libreadline.so
make
---
(you had mistakenly typed `libncurses' instead of `libreadline'), the
build completed successfully, and `./sage -t -long devel/sage-main/' had
all tests pass except for the following:
---
devel/sage-main/sage/tests/cmdline.py
devel/sage-main/build/lib.linux-x86_64-2.6/sage/tests/cmdline.py
devel/sage-main/build/sage/tests/cmdline.py
devel/sage-main/sage/misc/trace.py
devel/sage-main/build/lib.linux-x86_64-2.6/sage/misc/trace.py
devel/sage-main/build/sage/misc/trace.py
---
In my (perhaps inaccurate) estimation, these failures are related to
libreadline. In the terminal window, each doctest failure mentioned a
warning about readline being absent. I couldn't find a log file and
I've since closed that window, but I'm attaching the files left in
`~/.sage/tmp', in case they help.
This is likely related to the following message I receive upon loading Sage:
---
WARNING: Readline services not available on this platform.
WARNING: The auto-indent feature requires the readline library
---
readline functionality is indeed non-functional in my build of Sage. I
did have readline-common, libreadline6, libreadline6-dev, and
libreadline-dev installed before starting the build process.
This issue is not a deal breaker for me, as I almost always work from
the Sage notebook, but I thought you might want to know about this.
Thanks for the advice throughout this process.

Nope, that wasn't a mistake. ;-)
Readline uses libncurses (more precisely libtermcap or one of its
replacements), so the links are intended to get around the odd linker
script in /usr/lib/libncurses.so, which /usr/lib/libtermcap.so is a link to.
I.e., it should really have been
$ cd $SAGE_ROOT/local/lib/
$ ln -svf /lib/libncurses.so.5
$ ln -svf libncurses.so.5 libncurses.so
You could try that and then try to reinstall the R spkg with
$ cd ../.. # only in case you're still in $SAGE_ROOT/local/lib
$ ./sage -f spkg/standard/r-2.10.1.p4.spkg
[From another message:]
Btw, I meanwhile have a new readline spkg [1] you could give a try. (It
is based on readline 6.2 rather than 6.1, but that alone shouldn't make
much of a difference; the relevant part is a patch to the upstream
sources from Sage's side.)
I.e., you could install that (with './sage -i ...') and afterwards try
to (re)install the present R spkg (with './sage -f ...', to force the
reinstallation) in the configuration where it previously failed (i.e.,
*with* libreadline-dev installed I think).
(You should try that *without* any manually added links in
$SAGE_ROOT/local/lib, i.e.
$ rm -f $SAGE_ROOT/local/lib/libncurses.so*
$ ./sage -i /path/to/readline-6.2.p2.spkg
$ ./sage -f spkg/standard/r-2.10.1.p4.spkg

If that didn't work, you could also try:
$ cd $SAGE_ROOT/local/lib/
$ ln -svf /lib/libtinfo.so.5 libtermcap.so
$ cd ../..
$ ./sage -f spkg/standard/r-2.10.1.p4.spkg

Good news! To have sage-4.7.2.rc1 build properly on Ubuntu 11.10, all I
had to do was replace $SAGE_ROOT/spkg/standard/readline-6.1.pkg with
readline-6.2.p2.spkg (the spkg you provided) before running `make'.
`./sage -t -long devel/sage-main/' resulted in one doctest failure.
