Great!

The zlib module is the only one that is imported with the standard
mechanism, since it is imported when a zipfile is added to sys.path.
So, when it's filename has the wrong case the import will fail, and the
only solution would be to set PYTHONCASEOK=1 before.  Unfortunately,
this cannot be done somewhere in your Pythoncode, because it's too late
then.  So, if you insist on 'compressed': 1 (but why would you?) the
only solution that I see is to add
     _putenv("PYTHONCASEOK=1");
to the source file start.c, somewhere in the init_with_instance
function, near line 135, and rebuild py2exe.
