Same as bug #639558, but for the stable version, i.e. media-gfx/hugin-2016.2.0.
Emerges just fine against media-libs/vigra-1.11.0. You could consider stabilizing that.
(In reply to Jaak Ristioja from comment #1) > Emerges just fine against media-libs/vigra-1.11.0. You could consider > stabilizing that. yeah, you're right! I've created bug 652616 to stabilize 2018 version.
media-gfx/hugin-2016.2.0 is no longer in tree. While 2018.0.0 seems to suffer from bug #681318 and the like, hugin-2019.0.0 emerges just fine. Resolving this as OBSOLETE.
