 Replying to [comment:8 egall@…]:
 > Edit: gegl actually lists ffmpeg as an optional dependency, not a needed
 one: http://www.gegl.org/#_dependencies
 >
 > Perhaps the port for gegl could have its ffmpeg dependency moved to a
 variant? According to the link, libopenraw, libsdl, jpeg, openexr, and
 librsvg are also all optional dependencies; perhaps all of them could be
 moved to one big `+optional_dependencies` variant or something?

 Just because an upstream project considers some dependencies to be
 optional does not mean that we will necessarily make them optional in
 MacPorts.
