Thanks, that explains why the CygWin Python will not import the .pyd files:
>>> imp.get_suffixes() [('.dll', 'rb', 3), ('module.dll', 'rb', 3), ('.py', 'U', 1), ('.pyc', 'rb', 2)] Doesn't look like there's a way to get the CygWin Python to load .pyd files. So I guess I have to figure out why the build isn't working... -- http://mail.python.org/mailman/listinfo/python-list
