I've managed to get Sage 4.5 to build on FreeBSD (see http://wiki.sagemath.org/freebsd/sage-4.5 for details) and it seems to run (I'm still waiting for the test suite results) but it consistently gets segmentation violations on exit.
Running "sage -gdb" and just exiting at the prompt, I get:

The exact problem is unclear. The reported location: ~Commentator at
commentator.C:59 doesn't make sense because the give line number is
inside Linbox:nroot(), with ~Commentator significantly later in the
file. Unfortunately, there's no spkg-check for linbox but "make
check" passes except for test-gf2 (which won't compile). Does anyone
have any suggestions on where to look?
