[mod_python] mod_python module path

Hello all.
I'm starting with mod_python, and I'm thinnking about developing a web 
application using it. However, I have some python packages of my own, 
that i wanted to use, and don't know how to add them to the module path. 
I made a symlink in site-packages, to my module directory, and it works. 
However, I'll need to do it without administrator privileges. How is it 
possible? Is there any variable I should change?

Thanks in advance,

Pedro
