I'm in middle of @world update, and dev-lang/perl was updated already, but dev-perl/Pango was not updated yet.
[ebuild R ] dev-perl/Gtk2-1.249.920::gentoo USE="-test" 0 KiB
[ebuild R ] dev-perl/Pango-1.227.0::gentoo USE="test -examples -minimal" 0 KiB
dev-perl/Gtk2 fails to build with:
MakeMaker FATAL: prerequisites not found.
Pango not installed
If I not mistake, the fix would have something to do with subslots?

This is portage's problem, not much perl can do about it.
When X requires Y, portage's responsibility is to ensure Y is working before attempting installing X.
Portage is failing to do this and simply ordering the build order wrong.
So basically, what actually happens is portage tries to install X where Y is so broken its "practically not even installed".
"only" been a problem since 2007 ....
