RepoMan scours the neighborhood... KEYWORDS.dropped 2 media-gfx/inkscape/inkscape-0.91-r2.ebuild: arm media-gfx/inkscape/inkscape-0.91-r3.ebuild: arm The keywords got dropped because of bug 350630. This was likely related to the plotutils use mask, which now has been removed in commit 4351b3dfa4413d098d5174f049fc6b778ac6fda6. Just readding the keyword makes repoman happy.
Thanks, fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=11f8aaeadc56e2e7655caec587c5314373ad3388
