Comment 1 for bug 250772

I have gotten the same warnings along with it not working. This is due to the fact that the devs have added most of the phonon stuff in at the wrong locations.

libphonon-dev should install phonon headers to /usr/include/qt4/phonon
phonon-backend-gstreamer should install the plugin to /usr/lib/qt4/plugins/phonon_backend

Currently phonon is broken in intrepid due to the files being put into the improper locations. They seem to think it doesnt belong with the rest of QT even though it is a standard part of QT4.4.

All phonon related files need to be put into qt4 directories instead of kde or other non-qt4 related directories. Hopefully this will be fixed soon
