If that fails, unmerge rawstudio too. Run emerge -u @world then re-emerge
rawstudio. It may well clear the problem but even if it does not you are
now dealing with a single blocker on an up to date system.

Unemerge media-libs/libpng and media-gfx/rawstudio, get stuff like @system, 
Portage and Python updated first.

As a general rule when updating old systems, remove all the packages you 
installed on it, update the base system, and then reinstalling user apps will 
go easy.

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

2014-04-13 Thread Matthias Bethke 
For the first time in years portage is driving me crazy. I'm trying to
update my desktop after half a year in storage and coping with the Gnome
3.10 upgrade that I want to avoid because of systemd. And this is where
it always gets stuck:

So media-libs/libpng:0 is indeed installed, and it not only works but
| emerge -1vta `equery d libpng`
does work, too. That way I have already recompiled every single thing
that requires libpng, including rawstudio so IMAO it shouldn't even come
up during @world updating, and if there is some reason for to be
recompiled it should work just like when I say emerge -1 rawstudio.

I've run into a few blockers during this update run and Google has been
my friend for most of there, but here I only find some QT-related forum
entries that seem to be unrelated or offer solutions like masking some
libpng version
[http://forums.gentoo.org/viewtopic-p-7520134.html#7520134] that didn't
help and frankly sound rather voodoo.

Could anyone help me out here?

cheers,
Matthias

This sort of query is coming up a lot lately, a common suggestion to
help portage out is to use the --backtrack option with a high number
like 30 or 100.

Give that a try.

A second, blunt weapon, approach is to quickpkg libpng, unmerge libpng
then emerge rawstudio back (or even -avuND world) and let portage get on
with the business of figuring stuff out that will work
