Please add the following ebuild. It is a dependency for dev-tex/biber (bug #340353).
Created attachment 289579 [details]
I've added the ebuilds to ::perl-experimental. They can be added to ::gentoo when needed / all blockers of the parent bug are fixed.
I think it's not used by biblatex-biber-v0.9.9.
So closing for now.
Hm, i missed the other blocker :(
