I got it working. Had to install 1.27 beta linux patch then I had to copy the all the PAK files from the /baseq3 dir on the cd to /usr/local/games/quake3/baseq3, and all the files from /missionpack on the cd to /usr/local/games/quake3/missionpack, and it worked. Just fired up regular old quake 3 after than and clicked Team Arena. Wahoo!
