[vtkusers] Re: wxVTKRenderWindowInteractor.py fails on OSX with VTK Cocoa build

Not to burst your bubble, BUT Apple's X11 is based on Carbon also..
The only way to get 64 bit GUI _RIGHT NOW_ with OS X is to write it
purely in Cocoa. Last I heard you would need VTK CVS Head for this and
even then I think there are some problems.

Sean M. can chime in here with more answers..
