First, catch your rabbit. Somehow get KGoldrunner installed. Your GNU/Linux distribution has probably already packaged it for easy installation. Then place the .grl files in ~/.kde/share/apps/kgoldrunner/user/levels, creating this if it doesn't exist. Edit or create ~/.kde/share/apps/kgoldrunner/user/games.dat and add this line: 132 T dm KGoldRunner Expansion Pack Now run KGoldrunner and when you select New Game from the Game menu, you should see the KGoldrunner Expansion Pack listed.
