I'm curious:  what was the one character change?   And does your
original program still work for him?  Why did he install a different
version of numpy if things were working for him?

By the way, posting "x doesn't work" on a forum never gets you
any help, because clairvoyance is not real  :D.  Posting actual error
messages sample code does.

As someone mentioned, you don't "compile" anything in Python.
You can make a .exe file, though, using, as you know, py2exe.
I find using GUI2Exe (which requires you have wxPython) to make
things
much easier and then if you want to be even fancier, use InnoSetup to
make an installer.

Once you get a working script in py2exe/GUI2Exe, it is usually a snap
to make a new version of your .exe after changing your code a bit.

As far as then updating your .exe files with your non-Python friends,
you should search this newsgroup for Esky, which seems like a very
nice idea for doing this very thing.
