I got a libpng error, as mentioned on the FAQ here:
wiki:ProblemHotlist#libpng
This was the following error I got after installing py27-pyqt4 and the
required dependencies:
{{{
Traceback (most recent call last):
File "QtEvent.pyw", line 15, in <module>
from PyQt4.QtGui import *
ImportError:
dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/site-packages/PyQt4/QtGui.so, 2): Library not loaded:
/opt/local/lib/libpng12.0.dylib
Referenced from: /opt/local/lib/libQtGui.4.dylib
Reason: image not found
}}}
Forcing an upgrade (as stated in the FAQ) for py27-pyqt4, python27, and
libpng didn't work, however forcing an upgrade for qt4-mac fixed the
problem.

Comment:
I cannot explain why your qt4-mac was not already linked with libpng 1.4,
since libpng was updated to 1.4 over a year ago in r75159 and qt4-mac
received a revbump at the same time. So I do not know what action we could
now take to improve the situation.
