How to deploy a Phonon-dependent Qt4 / PyQt4 / python application on Mac OS X?

I wrote a cross-platform Qt4 / PyQt4 / python application, namely MyGreatApp, the latest version of which requires the Phonon module. MyGreatApp works fine on my machine on Mac OS X 10.6 Snow Leopard and, more generally, on any Mac where Qt4.4 is installed. However, innocent machines eagerly don't load Phonon:

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

It seems obvious that some executable files remain in the executable. Phonon material is included here:

$ find . -name "*phonon*" -print
./Contents/Frameworks/phonon.framework
./Contents/Frameworks/phonon.framework/phonon
./Contents/Frameworks/phonon.framework/phonon.prl
./Contents/Frameworks/phonon.framework/Versions/4/phonon
./Contents/plugins/phonon_backend
./Contents/plugins/phonon_backend/libphonon_qt7.dylib
./Contents/Resources/lib/python2.5/lib-dynload/PyQt4/phonon.so

And here are the commands install_name_toolthat I call after creating the application:

PLUGINSREF = /usr/local/Trolltech/Qt-4.4.3/plugins
QTLIB      = /usr/local/Trolltech/Qt-4.4.3/lib
PLUGINS    = dist/MyGreatApp.app/Contents/plugins
RESOURCES  = dist/MyGreatApp.app/Contents/Resources
PHONON     = phonon.framework/Versions/4/phonon
QTCORE     = QtCore.framework/Versions/4/QtCore
QTGUI      = QtGui.framework/Versions/4/QtGui

echo "Installing plugins"
mkdir -p "$PLUGINS"/phonon_backend
cp $PLUGINSREF/phonon_backend/libphonon_qt7.dylib "$PLUGINS"/phonon_backend
install_name_tool -change $QTLIB/$PHONON @executable_path/../Frameworks/$PHONON "$PLUGINS"/phonon_backend/libphonon_qt7.dylib
install_name_tool -change $QTLIB/$QTCORE @executable_path/../Frameworks/$QTCORE "$PLUGINS"/phonon_backend/libphonon_qt7.dylib
install_name_tool -change $QTLIB/$QTGUI  @executable_path/../Frameworks/$QTGUI  "$PLUGINS"/phonon_backend/libphonon_qt7.dylib

echo "Adding Panther compatibility when building on Leopard"
install_name_tool -change /System/Library/Frameworks/CoreVideo.framework/Versions/A/CoreVideo  /System/Library/Frameworks/QuartzCore.framework/Versions/A/QuartzCore "$PLUGINS"/phonon_backend/libphonon_qt7.dylib

echo "Installing dynamic libraries"
install_name_tool -change $QTLIB/$PHONON @executable_path/../Resources/lib/$PHONON "$RESOURCES"/lib/python2.5/lib-dynload/PyQt4/phonon.so
install_name_tool -change $QTLIB/$QTCORE @executable_path/../Resources/lib/$QTCORE "$RESOURCES"/lib/python2.5/lib-dynload/PyQt4/phonon.so
install_name_tool -change $QTLIB/$QTGUI  @executable_path/../Resources/lib/$QTGUI  "$RESOURCES"/lib/python2.5/lib-dynload/PyQt4/phonon.so

Any idea of ​​what goes wrong, or any hint of better diagnosis?

Qt ( ), , , "macdeploy_qt". (.. myapp.app "myapp" myapp.app/Contents/MacOS) "macdeploy_qt myapp.app", install_name_tool , , " " ( :)).
