Created attachment 389220 [details, diff] darktable-1.4.2.ebuild-depend_on_gtk-engines.patch media-gfx/darktable comes with its own gtkrc file, which uses the ClearLooks engine from x11-themes/gtk-engines:2. This package is presently *not* a dependency of Darktable ebuilds, resulting in darktable complaining about missing engine whenever it is started. Please find enclosed a patch which adds x11-themes/gtk-engines:2 to run-time dependencies of media-gfx/darktable. An alternative would be to introduce a new gtkrc file which does not use ClearLooks - such a file however would have to be maintained by Gentoo. Cheers, -- MS
Fixed in 1.6.0.
