The gqmpeg ebuild depends on mpg123 for it's mp3 support, but gqmpeg works fine with mpg321 and the README even suggests it as an alternative to the non-free mpg123. I believe the ebuild should be updated to depend on one or the other. The attached patch changes the behaviour to fix this, but favours mpg321 which may not be to everyone's taste. Thanks James
