oh sry, i didn't mention that i use linux too. 
in that case: here's how i set it up (warning: this is a bitch to do)
get the latest code from svn
svn co svn://svn.icculus.org/tremulous/trunk tremulous-svn-src/
then you will need to compile it (make sure you have sdl headers installed)
cd tremulous-svn-src
make
if you didn't get any errors, you will need to copy the new binary next to tremulous.x86 (name it tremulous-svn.x86 or something). also, copy tremulous-svn-src/ui/ to ~/.tremulous/base/ui/ (this will affect your regular version as well, but the lack of options was annoying anyway). then you need to get vcxzet's pk3's, and put them in ~/.tremulou/tremx/. (you can try compiling them, but i have had no success).
