Upstream merged a branch redoing notifications so its tests-optional patch no longer applies. It appears 789eedc52 in the branch actually broke it (tho didn't bisect to be sure), with the merge being 3c52fc3bc. Without that patch (and without USE/FEATURES=test) the build and merge now complete fine, so it seems the new version doesn't need a similar patch.
