I have already asked them actually because I needed to do the exact same 
thing. Basically, there is two options. a) Look into INSTALL_MASK in 
profile.bashrc or b) hack the ebuild to do the equivalent of "for i in 
$PYTHON_VERSION; do $i setup.py install; done"

The latter option was too much work for me and I needed a "now fix" so I 
did "ebuild <python module> unpack; cd $S; python2.4 setup.py install" 
where my usr/bin/python was a symlink to python2.5. This, as you can 
imagine, might cause file collisions, broken behavior, etc. But it did 
work for me.

Please use the above advice cautiously and definately don't ask for help 
with the above method from the python team. ;) It is a bad thing to 
install apps and bypass portage.
