The real question is, why are you mixing unstable marked libpng15 with stable marked xemacs?
Moving to xemacs maintainers anyway to say "It's time to stabilize new version of xemacs since libpng15 will go stable soon."
(In reply to comment #5) > Moving to xemacs maintainers anyway to say "It's time to stabilize new version > of xemacs since libpng15 will go stable soon." Not going to happen any time soon because xemacs 21.5 really isn't ready for stable. This will need to be fixed in 21.4 instead.
Blocking bug 354479 then.
To answer Samuli's question...I've had ~amd64 for libpng for so long, I forgot about it. I don't even remember why I put it in there. xemacs is the only failing package on my system out of the 25 which depend on libpng. It would probably be sufficient to modify the ebuild to indicate it depends on libpng prior to 1.5. equery d libpng shows: app-editors/xemacs-21.4.22-r1 (png ? >=media-libs/libpng-1.2) Perhaps that should be (( >= media-libs/libpng-1.2) && (<media-libs/libpng-1.5))?
Created attachment 287805 [details, diff] xemacs-21.4.22-libpng15.patch NOTE: To be applied *after* existing -large-images.patch
Thanks for the patch. Fixed in xemacs-21.4.22-r2.
