The MPlayer ebuild for 0.60 had a section to check for dxr3/hollywood+ support and patch the source for it if it is found, this part was NOT removed in the version bumps to MPlayer 0.90_pre and causes the ebuild to fail on systems with dxr3/hollywood+ support. Attached will be a patch against recent MPlayer ebuilds.
Created attachment 737 [details, diff] patch to correct mplayer ebuild behavior with em8300
