I do have USE=-phonon. I suspect that may be a required dependency in this case.

[Comment 1 Michael Palimaka (kensington) 2016-04-10 16:50:01 UTC]

I suspect your system is broken - khtml unconditionally requires phonon but that library appears to be missing.

[Comment 2 ta2002 2016-04-11 18:14:02 UTC]

This is actually more interesting (and puzzling) than I suspected when I did a very cursory look at this.

Phonon is installed.

$ equery uses phonon
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for media-libs/phonon-4.7.2:
 U I
 - - debug      : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see
                  https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
 - - designer   : Install plugin for dev-qt/designer
 + + gstreamer  : Add support for media-libs/gstreamer (Streaming media)
 - - pulseaudio : Add support for PulseAudio sound server
 + + qt4        : Add support for the Qt GUI/Application Toolkit version 4.x
 + + qt5        : Add support for the Qt 5 application and UI framework
 + + vlc        : Install VLC Phonon backend

Required files exist:

$ qlist phonon | grep libphonon4qt5.so.4
/usr/lib64/libphonon4qt5.so.4.7.2
/usr/lib64/libphonon4qt5.so.4

$ ls -al /usr/lib64/libphonon4qt5.so.4.7.2 /usr/lib64/libphonon4qt5.so.4
lrwxrwxrwx 1 root root     22 2016-04-09 14:00:12 /usr/lib64/libphonon4qt5.so.4 -> libphonon4qt5.so.4.7.2*
-rwxr-xr-x 1 root root 457416 2016-04-09 14:00:13 /usr/lib64/libphonon4qt5.so.4.7.2*

Revdep-rebuild shows nothing broken:

Please attach full build log + paste emerge --info.

Working now (after the latest round of KDE updates).
