[PyQt] PyQt4+Phonon problem

[zw g]

Dear List,


I try to use *PyQt4 + Phonon* to create a simple player on Mac OS X.
Every time i fire up it, it report the below information, and it can NOT
play any sound:


*WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend
plugin could not be loaded *


Does anyone know how to fix this?
Thanks.

Information for reference:
Mac OS X 10.7.5
Qt4 4.8.3
PyQt4 4.9.4      (compiled from source)
phonon 4.6.0    (installed by macports)


Gui
