Python Multiprocessing Error on Mac OS X

Question

I need to distribute a python application to some Mac users, the application works well on Windows, but on Mac OS X something is wrong. Multiprocessing does not work on Mac OS X due to http://code.activestate.com/lists/python-ideas/17811/ . Is there a way around the error:

'The process is forked and you cannot safely use this CoreFoundation functionality. You MUST execute exec (). Break for THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY _YOU_MUST_EXEC __ () for debugging. ''

Thanks so much for any help :)
