Just so's you know, I recently deinstalled python 2.2.1 from my Cygwin
installation and upgraded to python 2.2.1-1 (which inlcudes threading,
unlike its predecessor). I was delighted to find that the modules installed
in site-packages were still present - even mxODBC, which you may know is a
binary extension.

So it's probably almost as easy to let packages install where they naturally
go than have to track them and use special setup.py arguments to install
them somewhere else.

As far as your own scripts go, of course, you can choose not to use setup.py
and install them wherever you like.
