Ok, I see: # Minimal supported version of Qt. QT_PV="5.4.2:5" So, from bug 563898, I gather the problem was that Qt packages have been allowed to upgrade to 5.5 without taking QtWebKit with them. Is that correct? So, after https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=bf3cf2b99bb97b0ac13850a3537c72d0cc389f12, others won't encounter this? > > > # emerge -pv qtwebkit > > > > These are the packages that would be merged, in order: > > > > Calculating dependencies... done! > > [ebuild U ] dev-qt/qtwebkit-5.6.0:5/5.6::gentoo [5.4.2:5/5::gentoo] > > USE="gstreamer jit%* opengl printsupport webp -debug -geolocation% > > -gstreamer010 -multimedia -orientation% -qml {-test} -webchannel% (-udev%*)" > > 34,476 KiB > > You have qtwebkit-5.4.2 (which btw is no longer available in the tree), > while the rest of your Qt installation is at 5.5.1 or later.

I was filing the bug as it looks like a missing dependency on the QtWebKit version at first glance.

I was filing the bug as it looks like > a missing dependency on the QtWebKit version at first glance. Well the deps have already been fixed long ago. However you first need to upgrade to 5.5.1 to get the correct ones. We can't change the dependencies retroactively on already installed packages.
