How to install phonon with macports on mac osx pyside

Question

I am trying to use phonon with pyside on mac. I want to be able to play quicktime movies in widgets on a desktop app with pyside.

I installed phonon, qt and pyside from source via macports

$ sudo port -s -v install phonon qt4-mac
$ sudo port -s -v install py27-pyside

I can confirm the installs as follows

$ port installed phonon qt4-mac
The following ports are currently installed:
  phonon @4.6.0_1 (active)
  qt4-mac @4.8.5_0 (active)

I found a simple bit of code to test this ..

import sys
from PySide import QtCore, QtGui
from PySide.phonon import Phonon

app = QtGui.QApplication(sys.argv)
testPlayer = Phonon.VideoPlayer()
testMedia = Phonon.MediaSource('/path/to/media/test_MOV.MOV')
testPlayer.load(testMedia)
testPlayer.play()
testPlayer.show()

sys.exit(app.exec_())

however i get the following errors when running the code in pycharm.

Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.freedesktop.dbus-session.plist is loaded!

It looks like the backend isn't working properly and phonon isn't connecting to quicktime? If this is the case ho do i fix this? how do i set the plugin path? -- i couldn't find information for this for osx.

Or alternatively is there another better way to play quicktimes with audio within pyside instead of phonon?

thanks in advance.

Run the following commands, it seems those are listed, but not loaded

sudo launchctl load -w /Library/LaunchDaemons/org.freedesktop.dbus-system.plist
sudo launchctl load -w /Library/LaunchAgents/org.freedesktop.dbus-session.plist
