Comment(by thomas.haymore@…):

 Here's what ended up happening (in addition to steps above):

 1) When I tried to uninstall libpng, I discovered I had two versions
 installed, 1.2 and 1.4.
 2) I tried uninstalling only 1.2 and forcing 1.4 to upgrade, but that
 didn't work
 3) Uninstalled everything, libpng, qt4, and py26-pyside
 4) reinstalled qt4 and py26-pyside and dependents
 5) everything seems to work fine now

 Thanks for the help.
