Actually to clarify a bit here's what I see:

 >>> sys.prefix
'/usr/local'
 >>> sys.path
['', '/usr/local/lib/python25.zip', '/usr/local/lib/python2.5', 
'/usr/local/lib/python2.5/plat-linux2', 
'/usr/local/lib/python2.5/lib-tk', 
'/usr/local/lib/python2.5/lib-dynload', 
'/usr/local/lib/python2.5/site-packages', 
'/usr/local/lib/python2.5/site-packages/PIL']

I am thinking that the prefix is prepended to all the paths.

All my stuff lives in 'usr/lib/python2.5', so I was hoping by just 
changing my prefix it would set the rest of the paths accordingly.
