  It is a "deep dependancy".  kde-base/kdelibs-4.12.5-r1.ebuild has a
"COMMONDEPEND=" block which includes ">=media-libs/phonon-4.4.3".  And
media-libs/phonon-4.6.0-r1.ebuild has the following line...

REQUIRED_USE="|| ( aqua gstreamer vlc )"

  In gentoo, *ANY* kde app which runs on the kde infrastructure requires
phonon, and one of aqua/gstreamer/vlc, unless you resort to ugly hackery
as per http://permalink.gmane.org/gmane.linux.gentoo.user/276393
