Hi Achim, about ORG_ADD_CONTRIB and other faults that you pointed out in my ebuild: I'm sorry but I didn't manage to test this before going on holiday. Meanwhile I see there has been progress; see Ulrich Müller's comment at <https://bugs.gentoo.org/show_bug.cgi?id=466720#c6> and my reply. I just wanted to let everyone know, but I am currently unable to work on this.
