Here is the HOWTO that I read telling how to install an open arena mod.

I really like Open Arena, but wish it behaved better when running the original quake 3 program.
For those who are not willing to tolerate unlocking the levels every time they play (like me).
I have a modern OS solution which allows Quake 3 and Quake 3 Arena to operate exactly as
they did when originally released to the linux community. Just follow these simple instructions
to install Quake 3 with the ioquake engine. Download linuxq3apoint-1.32b.x86.run and
ioquake3-1.36-7.1.i386.run from where ever you can find them on the internet. Then as
non root user type:)
xhost +
(Then change the POSIX version to overcome the
incompatibility with the old loki installer
become root user & type:)
export _POSIX2_VERSION=199209
(Then install the old quake3 apoint release type:)
sh linuxq3apoint-1.32b.x86.run
(Now get rid of that POSIX version type:)
export _POSIX2_VERSION=
(Then install the modern ioquake release type:)
sh ioquake3-1.36-7.1.i386.run
(Copy all the .pk3 files from the /usr/local/games/quake3/baseq3
directory into the /usr/local/games/ioquake3/baseq3 directory.
Ioquake does not include these files, but won't run the original quake3
without them which is the only reason we installed the old quake3
apoint release. The old quake 3 directories can now be deleted type:)
rm -rf /usr/local/games/quake3
(Copy the PAK0.PK3 file from the original Quake3 CD into the
/usr/local/games/ioquake3/baseq3 directory. Now you can exit root
mode and the ioquake engine will run the original quake3 program
perfectly. If you want to add Team Arena, then copy the PAK0.PK3
file from the original Team Arena CD to the /usr/local/games/ioquake3/missionpack
directory.) Enjoy
