See the attached patch for adding a mac use flag and related deps to the ebuild in order to support the Monkey's Audio format. Note that media-sound/aqualung and media-sound/xmms2 are the only ebuilds that also use the mac use flag so it will have to be added as a local use flag.
Created attachment 244487 [details, diff] Add Monkey's Audio support Ebuild changes: * Add mac use flag * Add optional deps on media-sound/mac and mplayer
Note that the use flag could also be called ape. I chose mac since a couple other packages were already using it.
Added to the latest ebuild revision.
