1 I've been running number theory code for a few weeks, so haven't been
2 updating my machine too often...
3
4 I for the last day or so I'm in a run my "pretendupdate" script, look at
5 the results, decide whether to run ufed or bleep with package.use....
6 run the pretendupdate script again, do something while it computes, come
7 back to it hours later, and repeat the cycle... This is really getting
8 silly and I'm starting to suspect that I'm stuck in useflag hell and
9 there isn't a solution to this.

16 These are the packages that would be merged, in order:
17
18 Calculating dependencies... done!
19
20 !!! Multiple package instances within a single package slot have been pulled
21 !!! into the dependency graph, resulting in a slot conflict:
22
23 dev-libs/icu:0
24
25 (dev-libs/icu-56.1:0/56::gentoo, ebuild scheduled for merge) pulled in by
26 (no parents that aren't satisfied by other packages in this slot)
27
28 (dev-libs/icu-55.1:0/55::gentoo, installed) pulled in by
29 dev-libs/icu:0/55=[abi_x86_32(-),abi_x86_64(-)] required by
30 (dev-qt/qtcore-4.8.7-r1:4/4::gentoo, installed)

36 It may be possible to solve this problem by using package.mask to
37 prevent one of those packages from being selected. However, it is also
38 possible that conflicting dependencies exist such that they are
39 impossible to satisfy simultaneously. If such a conflict exists in
40 the dependencies of two different packages, then those packages can
41 not be installed simultaneously.

44 page or refer to the Gentoo Handbook.

47 !!! The ebuild selected to satisfy
48 ">=media-libs/mlt-0.9.8-r1[ffmpeg,kdenlive,melt,qt5,sdl,xml]" has unmet
49 requirements.
50 - media-libs/mlt-0.9.8-r2::gentoo USE="ffmpeg fftw gtk kde kdenlive lua
51 melt opengl python qt5 sdl xine xml -compressed-lumas -debug -frei0r

55 The following REQUIRED_USE flag constraints are unsatisfied:
56 kde? ( qt4 )
57
58 The above constraints are a subset of the following complete expression:
