Please mark gtk-engines-rezlooks ~amd64. I tested it and it compiles and runs nicely. It's quite stable. Pretty, too! :) Also, please fix the existing ebuild to use ${PV} in SRC_URI instead of hardcoding the version number. Thanks!
Done. I didn't modify SRC_URI, since ${PV} is rather pointless with such braindead naming scheme. If compnerd wants to modify it... that's up to him ;-)
