minimum python for distribution on Windows

[Bob Roberts]

I just tried out py2exe, and it worked great.  Is it possible to do
something similar, but with my python source code still available (and
able to be modified)?

I tried just copying my source code, python.exe, and the modules I use
into a new directory, but it keeps complaining about not having a lot
of modules, such as "site", that I never imported.
