To me, that looks like you're trying to build something called "library.zip" 
and .zip isn't an allowed file type extension.

If you change it to "library.exe" does it work?

Also, I consider this a bug in py2exe:

- it's an abuse of assert, using it to check user-supplied input;

- it's a failing assertion, which by definition is a bug.
