Re: [pygame] pygame on OSX (10.2.1)

All you really need to do is add in -framework Cocoa to the link.. I  
don't recall exactly where this happens, but it should be in  
config_darwin.py

Dynload is the dynamic run-time linker used by Darwin and OS X (akin to  
.dll's on windows, .so's on linux.. but with some novel features  
primarily for Objective C).
