[SciPy-user] weird error in mod_python (3.1.4.r1) /scipy (0.4.8)/gentoo (~x86) web application

This may be un-reproducible, and it does NOT happen within ipython
shell, but I am getting the backtrace below when trying to import
scipy within my application.  I would guess it has to do with the very
outdated ebuild of mod_python, (see the gentoo bug: 
http://bugs.gentoo.org/show_bug.cgi?id=123852), but just in case
anybody has any quick fixes, please let me know.

I have restarted Apache numerous times to make sure there isn't some
weird cache thing going on (the source of most of my phantom bug
reports).  Scipy 0.3.2 does not have this problem.

Backtrace follows. (6), with LcUtil.py, is where it tries to import
and errors out.
