The same way as /path/to/WSGIHome/lib/python2.5/site-packages, I'd
presume. That is, I have no clue, really. I think virtualenv and/or
easy_install automagically take care of that.

The /path/to/SandBox/lib/python2.5/site-packages directory contains a
.pth file with the following contents:
/usr/share/python-support/python-subversion
so it seems to get added allright.

I'm using the trac.wsgi script generated by trac-admin's deploy
command modulo the sys.stderr logging you suggested. FWIW, I've
attached the script.
Hope this helps and thanks for helping me trouble shoot this.
