Ok, I needed the libgl1-mesa-dev and also libxxf86vm-dev to continue.
I am stopped after that, with this error
/usr/bin/ld: skipping incompatible /home/kao/maratis-read-only/3rdparty/openal/linux/libopenal.so when searching for -lopenal

scons: *** [build/linux2/release/Examples/ManualUse/ManualUse] Error 1
scons: building terminated because of errors.
The libs are already installed,
locate libopenal.so libsndfile.so
/usr/lib/x86_64-linux-gnu/libopenal.so
/usr/lib/x86_64-linux-gnu/libopenal.so.1
/usr/lib/x86_64-linux-gnu/libopenal.so.1.13.0
/usr/lib/x86_64-linux-gnu/libsndfile.so.1
/usr/lib/x86_64-linux-gnu/libsndfile.so.1.0.25
But I suspect that the scons have problem with them because they are build for an 64bits platform.
I tried to fool it with this, but without success:
sudo ln -s x86_64-linux-gnu/libopenal.so lib32/libopenal.so
I could try to install the lib32 but it will not solve the real problem, in my opinion.
