I didn't check that www-client/firefox-25.0-r1 was actually requiring
>=media-libs/libpng-1.5.17[apng]
Why did -t (tree) not show www-client/firefox-25.0-r1 pulling libpng?
--tree (-t)
Shows the dependency tree for the given target by indenting
dependencies. This is only really useful in combination with --emptytree or
--update and
--deep.
So I just masked www-client/firefox until stable libpng, that isn't itself
broken or introduced regressions, catches up. Gentoo's history with libpng
compels me to keep it arch. ;)
I can't understand the *need* for the new slot/subslot philosophy. In the
former methodology we would have:
workstation ~ # eshowkw media-libs/libpng
Keywords for media-libs/libpng:
| | u |
| a a p s | n |
| l m h i m m p s p | u s | r
| p d a p a 6 i p c 3 a x | s l | e

What was the problem with this?
