Hej guys,
I just noticed this project (saw it on happypenguin.org) and I love it already
Keep up the great work!
Anyway, I checked out the svn tree and tried to build it.
With configure I used the --enable-release --enable-mmx options.
But make barfs:
* [UFO] src/game/q_shared.c

make: *** [release-linux-gnu-i386/client/game/q_shared.o] Error 1
A quick search revealed the solution.
Changing CFLAGS in the Makefile to this:
CFLAGS=-g -O2 -msse3
(-msse3 added)
For the record, I'm running Slackware current (32 bit distro) on my AMD 64 machine.
