I have a fvwm system. KDE has been the suck since 3.5.x because qt turned to crap with 4.0. -- IQ is a measure of how stupid you feel. Powers are not rights.

However, portage doesn't exactly make it easy for you with the output. Mere information is often obfuscated and looks like stuff you must fix, whereas the real nuggets can be hidden in the noise. Often running without -v can help considerably.

Two separate things result in different version of Qt being pulled into the problem solution. And it's exactly the form you'd expect. The first chunk is really saying that icu-56.1 is the most recent version and all other things being equal, that's the one portage would install. The second chunk is saying that qtcore-4.8.7-r1 requires icu-55.1 (not the most recent), so portage spews forth heaps of junk to helpfully let you not figure it out. What portage really should say is more like: Most recent version of icu (icu-56.1) not installed due to these requirements: qtcore-4.8.7-r1 requires icu-55.1 Ignore the multiple OMG! bangs before all of the above output > > > > It may be possible to solve this problem by using package.mask to > prevent one of those packages from being selected.

What you need to do now is set one of the following combinations in package.use for mlt: USE=-kde qt4 -qt5 USE=kde qt4 -qt5 On a plasma system like you have this will probably cause similar issues for other packages, so you must iteratively solve those as well till no more inconsistencies remain.

[gentoo-user] useflag hell.
I've been running number theory code for a few weeks, so haven't been
updating my machine too often...
I for the last day or so I'm in a run my "pretendupdate" script, look at
the results, decide whether to run ufed or bleep with package.use
run the pretendupdate script again, do something while it computes, come
back to it hours later, and repeat the cycle... This is really getting
silly and I'm starting to suspect that I'm stuck in useflag hell and
there isn't a solution to this.
tortoise ~ # ./pretendupdate
These are the packages that would be merged, in order:
Calculating dependencies... done!
!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:
dev-libs/icu:0
(dev-libs/icu-56.1:0/56::gentoo, ebuild scheduled for merge) pulled in by
(no parents that aren't satisfied by other packages in this slot)
(dev-libs/icu-55.1:0/55::gentoo, installed) pulled in by
dev-libs/icu:0/55=[abi_x86_32(-),abi_x86_64(-)] required by
(dev-qt/qtcore-4.8.7-r1:4/4::gentoo, installed)
^^
It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.
