I'm running Enthough 64 bit Python on Mac OS X, 10.7.4.  When I run one of 
the 'enaml' widget_gallery example programs, it tries to load quicktime, 
which is apparently only available as a 32 bit framework.  This results in 
a crash.

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

This application works perfectly fine without Quicktime, but crashes trying 
to load 32 bit Quicktime on a 64bit OS.

I've tested the following patch, which maps OSError to an ImportError.

Could one of the developers commit this to the source repository?
