Media-sound/soundkonverter needs kde-3.5 which i should cleanup.
kde-base/kdelibs:3.5 is still required by stable koffice-1.6.3, so it won't be removed before that anyway. but yes, soundkonverter must die, replaced by e.g. media-sound/soundconverter
nevermind, they released a kde4 version. yay. 1.0.0_alpha1 in portage
