it works now!

I think I was missing some devel packages related to SDL ( not sure which one since I installed a bunch of them just to be sure).
If anyone else wants to try:
required dependencies should be: make cmake gcc-c++ mercurial zlib-devel libpng-devel libjpeg-devel libvorbis-devel libSDL-devel openal-devel mercurial libSDLmm0.1-devel libSDL_mixer-devel
then type on a shell as root:
hg clone http://hg.icculus.org/icculus/lugarumkdir lugaru/buildcd lugaru/buildcmake ..makemake installto launch the game type:
/usr/local/lugaru/lugaru
