Xmahjongg is a singleplayer mahjong tile game. It works independant of your window manager so you only need a minimum set of packages. I've tested the ebuild and it works on my machine. The ebuild sed's the Makefile, because the DESTDIR var isn't added on some places by default.
Created attachment 6072 [details] ebuild file for xmahjongg-3.6.1 Ebuild file, everything seems to work OK.
