Hey!

I recently did some ia64-hpux hacking in prefix, and i stumbled over
alittle problem:

the native linker collects -L options on the command line, and python
uses -L. while building. this results in . beeing in rpath.

now when $PWD == $S, there is libpython-*.so, and executing the already
installed python finds (through rpath ".") this local libpython. this
(although binary exactly the same) refuses to load installed extensions
(Fatal Python Error: ....).

The problem was caused by the filter-bash-environment.py call in
ebuild.sh, _only_ during the "test" phase seemingly.

the attached patch fixes the problem for me - what do you think? I guess
there are better ways to tackle the problem, but i needed to get this to
work ;)

Cheers, Markus
