I emerged app-games/teg It emerged almost fine (see bug #19050). Now when i want to play that game, i just cannot use 'tegclient', but i have to use /usr/games/bin/tegclient I believe bug exists with many other ebuilds...
echo $PATH and make sure you are in the games group?
try running `env-update` and that the file /etc/env.d/90games exists before you do
