MAC USERS

Getting pymunk working on the mac is a bit tricky. A hardworking duo on irc produced a mac (intel) version of the Chipmunk shared library:

http://dump.omgcats.com/libchipmunk.dylib

If you've installed pymunk the typical way (as root, python setup.py install) you might need to place this library in the following place:

/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/pymunk-0.8-py2.5.egg/pymunk/libchipmunk.dylib

Two people have gotten this game running on Mac so it is possible.
