I think media-sound/qjackctl/qjackctl-0.2.23.ebuild should be removed, since there is a newer version which builds cleanly with Qt4 - why keep the old version around?
Other ebuilds inheriting the removed qt3, kde or kde-functions eclasses: $ egrep -l 'inherit.*(kde|qt3)' */*/*.ebuild media-sound/chionic/chionic-1.0.1.ebuild media-sound/freecycle/freecycle-0.6.1.1_alpha.ebuild media-sound/kguitar/kguitar-0.5.ebuild media-sound/kmidimon/kmidimon-0.5.0.ebuild media-sound/ktabedit/ktabedit-0.0.8.ebuild media-sound/ldrum/ldrum-0.6.0-r1.ebuild media-sound/openoctave-midi/openoctave-midi-9999.ebuild media-sound/qmidicontrol/qmidicontrol-0.0.1b.ebuild media-sound/simsam/simsam-0.1.7.ebuild media-sound/tuneroid/tuneroid-0.9.5.ebuild They should probably be masked, since they can only be built after adding the kde-sunset overlay. kmidimon has recent releases ported to KDE 4 in official portage, so it should also be removed from proaudio. kguitar and ktabedit have KDE 4 support in SVN but not released yet. The openoctave-midi ebuild is for OOM1 - the project has a new codebase, OOM2 but I'm not familiar with either. simsam has a newer version (0.1.8) - I haven't checked whether it still needs Qt 3. The others don't seem to be developed any more.
