That's me who updated this page based on whatever I can make sense of....

This Phonon business is a mess (a communication mess) and I don't find it easy 
to really know what is going on, either from Phonon KDE people or from Qt 
people...

For example I am not sure if Qt 4.7 needs to be installed in order for this 
Phonon from Qt 4.7 to work (remember, this techbase page is for people 
building from scratch and on their own).
Personally I get a KNotify crash linking to Qt 4.7 phonon gstreamer in a new 
clean KDE 4.5 branch build and new clean install...

Summary: don't rely on that techbase page but please do amend it if you are 
sure of any information!

PS: building trunk on its own is getting more and more difficult!
