Mac OS X: pyglet

installed pyglet
tried a simple app and run, get the following error:

OSError: dlopen(/System/Library/Frameworks/QuickTime.framework/QuickTime, 6): no suitable image found.  Did find:
 /System/Library/Frameworks/QuickTime.framework/QuickTime: mach-o, but wrong architecture
 /System/Library/Frameworks/QuickTime.framework/QuickTime: mach-o, but wrong architecture

found a link: https://groups.google.com/forum/?fromgroups=#!topic/pyglet-users/mvvIo7NotBo

so run the command in Terminal: "defaults write com.apple.versioner.python Prefer-32-Bit -bool yes"
to set python to run in 32 bit mode
and then compile app again. no problem.
