Subject: [gentoo-user] Blockers problem: no ebuilds to satisfy "media-libs/libpng:0/0="

1 For the first time in years portage is driving me crazy. I'm trying to
2 update my desktop after half a year in storage and coping with the Gnome
3 3.10 upgrade that I want to avoid because of systemd. And this is where
4 it always gets stuck:
5
6 | aldous ~ # emerge --keep-going --jobs=5 -DNuvta @world
7 |
8 | These are the packages that would be merged, in reverse order:
9 |
10 | Calculating dependencies... done!
11 |
12 | emerge: there are no ebuilds to satisfy "media-libs/libpng:0/0=".
13 | (dependency required by "media-gfx/rawstudio-2.0-r1" [installed])
14 | (dependency required by "@selected" [set])
15 | (dependency required by "@world" [argument])
16
17 | aldous ~ # eix libpng
18 | [I] media-libs/libpng
19 | Available versions:
20 | (1.2) 1.2.50-r1 ~1.2.51
21 | (1.5) 1.5.17-r15 ~1.5.18
22 | (0) 1.6.8(0/16) ~1.6.9(0/16) ~1.6.10(0/16)
23 | {apng neon static-libs ABI_MIPS="n32 n64 o32" ABI_X86="32 64 x32"}
24 | Installed versions: 1.6.8(09:32:10 PM 03/29/2014)(apng -neon -static-libs ABI_MIPS="-n32 -n64 -o32" ABI_X86="64 -32 -x32")

28 So media-libs/libpng:0 is indeed installed, and it not only works but
29 | emerge -1vta `equery d libpng`
30 does work, too. That way I have already recompiled every single thing
31 that requires libpng, including rawstudio so IMAO it shouldn't even come
32 up during @world updating, and if there is some reason for to be
33 recompiled it should work just like when I say "emerge -1 rawstudio".
34
35 I've run into a few blockers during this update run and Google has been
36 my friend for most of there, but here I only find some QT-related forum
37 entries that seem to be unrelated or offer solutions like masking some
38 libpng version
39 [http://forums.gentoo.org/viewtopic-p-7520134.html#7520134] that didn't
40 help and frankly sound rather voodoo.
41
42 Could anyone help me out here?
43
44 cheers,
