Yes, but you need two things:
1. Change your .pth file to read:
2. Create a distutils.cfg in /usr/lib/python2.3/distutils/ with the
contents I mentioned before.
Basically, without #1, .pth files in
/usr/local/mojam/lib/python2.3/site-package won't be processed by Python,
and without #2, setuptools won't know that Python is processing the .pth files.
