hi. the build fails compiling PARI/GP. it looks (see log bits below)
as if gcc isn't obeying its -I flags, since readline/readline.h appears
to be coming from /usr/include rather than from sage's local/include.
this is gcc 4.2 (llvm-based):

any suggestions?

i still don't know what causes this problem. but, i created a new user on my machine with a very bland environment, and ran the build from there. while the build is not yet finished, PARI/GP built just fine.
(as i said, i *did* move fink, etc., out of the way, but the build still failed. so, something else in my environment, perhaps -- though they shouldn't -- C_INCLUDE_PATH or CPLUS_INCLUDE_PATH were being searched before the -I<dir>s.)
(as i said, i *did* move fink, etc., out of the way, but the build still failed. so, something else in my environment, perhaps -- though they shouldn't -- C_INCLUDE_PATH or CPLUS_INCLUDE_PATH were being searched before the -I<dir>s.)

Everything in the compile line looks fine, so something in your environment...

may be getting in the way. In addition to making your PATH "plain vanilla", you might try nullifying a few of those _PATH variables.
I don't know that this problem has been seen before, but let us know if that clears it up with your login.
What apps use the above variables?
Thanks,
Justin
PS: on my 10.8.2 system, I have the "stock" readline includes in place, and they did not cause a problem with the build.

Could you list your environment variables within Sage?

Start a Sage shell:
$ ./sage --sh
And now ask for all environment variables:
$ env

Starting subshell with Sage environment variables set. Don't forget
to exit when you are done. Beware:
* Do not do anything with other copies of Sage on your system.
* Do not use this for installing Sage packages using "sage -i" or for
running "make" at Sage's root directory. These should be done
outside the Sage shell.
Bypassing shell configuration files...

C_INCLUDE_PATH / CPLUS_INCLUDE_PATH are overriding the default gcc header search path. This is why compilation is failing. Did fink put in these system-wide environment variables? Thats seriously effed up.

no, they come from my .bashrc. they've been "there" since 2008. sadly,
i no longer remember (nor documented) the reason they ended up there.
the gcc man page is a bit ambiguous:
----
CPATH
C_INCLUDE_PATH
CPLUS_INCLUDE_PATH
OBJC_INCLUDE_PATH
Each variable's value is a list of directories separated by a special
character, much like PATH, in which to look for header files. The
special character, "PATH_SEPARATOR", is target-dependent and
determined at GCC build time. For Microsoft Windows-based targets it
is a semicolon, and for almost all other targets it is a colon.
CPATH specifies a list of directories to be searched as if specified
with -I, but after any paths given with -I options on the command
line. This environment variable is used regardless of which language
is being preprocessed.
The remaining environment variables apply only when preprocessing the
particular language indicated. Each specifies a list of directories
to be searched as if specified with -isystem, but after any paths
given with -isystem options on the command line.
----
but i read (past and present tense) this as saying that C_INCLUDE_PATH
is searched *after* any -I<dir> statements on the command lines (in
which case, the -I<dir> statements Sage puts on the command line would
have had the local directories searched before these). do you know, are
they, in fact, search *before* the -I<dir>? that would certainly
explain it.
cheers, Greg

No its first -I<dir>, then *_INCLUDE_PATH, then the path thats hard-wired into the compiler. But since Sage builds its own compiler you are effectively overriding the search path.

Volker,
however, this doesn't explain the failure i was having, where
----
gcc -c -I. -I../src/headers -I../src/language
-I/Users/minshall/src/import/sage/sage-5.4.1/local/include -O3 -Wall
-fno-strict-aliasing -fomit-frame-pointer -g -o gp_rl.o
../src/gp/gp_rl.c
----
(i.e., with -I<...>/sage-5.4.1/local/include is on the command line)
appears to have picked up the <readline/readline.h> from /usr/include,
rather than from <...>/sage-5.4.1/local/include.
or, am i missing something? (maybe i don't understand your second sentence?)

If the directory is already in the built-in search path (like /Users/minshall/src/import/sage/sage-5.4.1/local/include if you use the gcc that Sage compiled) then the -I option is ignored.
-Idir
Add the directory dir to the head of the list of directories to be searched for header files. This can be used to override a system header file, substituting your own version, since these directories are searched before the system header file directories. However, you should not use this option to add directories that contain vendor-supplied system header files (use -isystem for that). If you use more than one -I option, the directories are scanned in left-to-right order; the standard system directories come after.
If a standard system include directory, or a directory specified with -isystem, is also specified with -I, the -I option will be ignored. The directory will still be searched but as a system directory at its normal position in the system include chain. This is to ensure that GCC's procedure to fix buggy system headers and the ordering for the include_next directive are not inadvertently changed. If you really need to change the search order for system directories, use the -nostdinc and/or -isystem options.

ah! got it. so, the Sage-compiled gcc includes .../local/include as
"a standard system directory" (and, is also on the command line via
-I). that explains it.
thanks!
