Comment (by jwhowarth):

 A few notes on how upstream has wired in the PyQt support. Pymol defaults
 to using PyQt if available and reverts to the Tk interface if it can't be
 found. However on darwin, the pymol display window only renders properly
 if pymol is built with the --osx-frameworks option passed to setup.py. So
 on darwin, a single build really can't render properly on both Tk and X11.
 If the packaging were enhanced to support a -x11 variant that would have
 to be built without the --osx-frameworks setup.py option. Also, since
 pymol now defaults to using PyQt if available, such a -x11 variant would
 have to explicity pass '-N pmg_tk' to the shell script that starts up
 pymol in order to suppress the use of PyQt.
