Seems to work fine, at least when used in app-misc/gramps and media-gfx/darktable, and stabilising it would pave the way for stabilisation of newer versions of the aforementioned two packages.
By the way, seeing as I was the person who got this ebuild into the tree I can oversee its stabilisation as well. With permission from the sci-geo project, of course.
Target keywords: amd64 x86
amd64 stable
x86 stable. Closing.
