A simpler way to do this is to use virtualenv.
$ virtualenv --no-site-packages YourEnv
$ . YourEnv/bin/activate
$ cd YourProject
$ python setup.py develop
(I'm not sure on the Windows commands, although I assume they exist
and are just as trivial as the Unix ones.)
Now, there is a link from the lib/python2.6/site-packages files to
YourProject. (Or Python2.7 or whatever version you are using.)
I'd also look at using Paster to create the package. It gives you a
pretty decent setup for straight up Python packages.
