Created attachment 439992 [details] emerge --info Tried switching my profile from desktop to desktop/plasma...after running into issues building phonon, I demoted Qt 5 libraries from ~amd64 to amd64 and rebuilt under the desktop profile...this basically took me from Qt 5.6 to Qt 5.5. I then switched profiles to desktop/plasma and gave emerge -auND --with-bdeps=y @world another shot. phonon built this time, but now I'm stuck on baloo-widgets. Logfiles and other such files will be attached shortly.

You should rebuild KDE Frameworks 5.21 after the Qt downgrade.
Trying that now...had gotten baloo-widgets to build with Qt 5.6 installed, but other bugs and forum messages indicate that 5.5 might be preferable. Will post again once the build's complete (currently downgrading Qt to 5.5 again).
Rebuilding kwallet also required rebuilding libdbusmenu-qt, phonon, and gpgmepp to get rid of undefined references to Qt 5.6. Trying again to see if other packages will cause similar failures.
The rest of the kde-frameworks/* packages rebuilt without further issue...moving on to revdep-rebuild.sh.
For the record, I don't see any issues wrt Qt-5.6.1. There sure are, but the fixes compared to 5.5.1 outweigh by far. Any way, you should settle with one version for once...
revdep-rebuild finally finished...everything's rebuilt. One motivation for downgrading Qt was to switch keywords from ~amd64 to amd64. I had 25 Qt-related packages keyworded, and every time some package needed another package keyworded, it caused breakage until I figured out what needed to be added. I'll go ahead and close this out as resolved.
