It does seem to work, but it segfaults on exit:

Any ideas on how to proceed?
I did a "sage -gdb" and it suggests that the problem might be to do
with
~Commentator in commentator.C. This is part of the linbox subpackage. I
did a google and found this:
http://trac.sagemath.org/sage_trac/ticket/11718
Does construction and/or deconstruction of Commentator tend to cause
problems?
I fixed the problem as follows:
sed -i .bak -e 's/Commentator/Commensator/g' \
"$SAGE_ROOT"/local/lib/liblinboxsage.so.0
That way sage didn't get confused between the Commentator that appears
in liblinbox and liblinboxsage.
Now I am getting a different segmentation fault, for which unfortunately
gdb provides no clues.
Can you still post what output/debugging info you have?
I am in the process of compiling with the "-g" option set. I'll send you
the output when this is done.
The "-g" option didn't seem to help one bit. This is what I got.
Not all of the subpackages respect CFLAGS or CXXFLAGS. But I don't know
if that is the reason the symbols are not showing up.
Any advice?
