I was able to get rid of this error by installing a new version of a
Framework build for libpng from
http://ethan.tira-thompson.com/Mac_OS_X_Ports.html
I also switched to using the non homebrew version which I installed from
source using "python setup.py install".
Now I can get the pymol window to show up and also import pymol inside
python scripts without any error.
But as expected I cannot get the external GUI to work.
I tried installing Pmw and it complains about "tkinter" . Once I force it
to use the Tkinter as tkinter
import sys,Tkinter
sys.modules["tkinter"] = Tkinter
Then the Pmw window does not show up and crashes.
These are all old issues I am sure and I am hoping there is an easy fix.
Sorry for using a 32 bit OSX machine running 10.6.8..but I recently
resurrected it with a SSD and it actually runs faster than my Ubuntu Linux
machine running 13.04.
