 Installed PySide through macports with dependencies, but when import
 module in python, get following error:

 {{{
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ImportError:
 dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6
 /site-packages/PySide/QtGui.so, 2): Library not loaded:
 /opt/local/lib/libpng12.0.dylib
   Referenced from: /opt/local/lib/libQtGui.4.dylib
   Reason: Incompatible library version: libQtGui.4.dylib requires version
 45.0.0 or later, but libpng12.0.dylib provides version 44.0.0
 }}}


 I have already tried:


 {{{
 sudo port selfupdate
 sudo port upgrade outdated
 }}}


 and


 {{{
 sudo port -n upgrade --force libpng
 }}}


 All with no effect.  I'm using a Mac 10.6.
