When media-gfx/enblend configures, it just searches for /usr/bin/mogrify, and that program is provided by both media-gfx/imagemagick and media-gfx/graphicsmagick[imagemagick] Reproducible: Always Actual Results: media-gfx/enblend requires media-gfx/imagemagick Expected Results: media-gfx/enblend could require either media-gfx/imagemagick or media-gfx/graphicsmagick[imagemagick]
Created attachment 410872 [details, diff] Patch for current stable media-gfx/enblend ebuild
Thanks, >=media-gfx/enblend-4.1.3-r2 depends on virtual/imagemagick-tools which allows you to use one of the two implementations.
