Then perform the following commands:
tar -xzf red-blue-quake2-0.1.tar.gz
ln -s ../gamei386.so
ln -s /path/to/quake2/baseq2/pak*.pak ./
echo "." > /etc/quake2.conf
./quake2 +set vid_ref softx +set vid_gamma 0.5 +set cl_stereo_separation 1.5
And that's it! (At least in theory, drop me a line if it doesn't work for you.) Remember to become root before writing to /etc/quake2.conf (you can play as a normal user). Experiment with the cl_stereo_separation value (you can adjust it from the console, no need to restart).
Here are some screenshots if you want to know what it looks like:
