I think this is very on topic. It's very useful feedback from a SAGE end user,
and I strongly encourage all SAGE developers to read it. Also, if anybody
else notices something like this online, I encourage them to post it
to sage-devel.
Thanks Martin!

Regarding the review, which mentions the stats package R, a lot of people have
written me off list about creating an interface to R. Note that there
has been a Python <--> R
interface since before SAGE was ever written:
I haven't used it, but imagine it would be easy to install into SAGE.
(??) If somebody
investigates, please post their experiences.

>From the installation instructions for rpy:
...(b) Then, configure the path to the R library. You have several
ways to do
this (substitute RHOME with the path where R is installed, usually
/usr/local/lib/R):
o make a link to RHOME/bin/libR.so in /usr/local/lib or /usr/
lib, then
run 'ldconfig',
o or, put the following line in your .bashrc (or equivalent):
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:RHOME/bin
o or, edit the file /etc/ld.so.conf and add the following
line:
RHOME/bin
and then, run 'ldconfig'.
To accomplish this in the spkg-install script, should I do the first
option
in SAGE_ROOT/local/lib?
No, SAGE_ROOT/local/lib is in LD_LIBRARY_PATH anyway. libR.so should
go in there. Then it is automatically found when requested by SAGE. To
run ldconfig one needs root, so that is not an option. Why a lib
should end up in $RHOME/bin seems rather odd to me.
