0.7.1 Source - Ubuntu Linux - Can't compile

Hi guys,
I'm used to compile each version of STK..recently I switched to Ubuntu 11.04 beta and tried to compile 0.7.1 version..
I've installed the following dependencies:
libopenal-dev
libopenal1
libogg-dev
libvorbis-dev
irrlicht1.8
irrlicht1.8-dev
libcurl3
libcurl4-openssl-dev
./configure runs without any problem
make runs but eventually reports:
states_screens/race_gui_base.cpp:31:21: fatal error: GL/gl.h: No such file or directory
compilation terminated.
make[2]: *** [race_gui_base.o] Error 1
make[2]: Leaving directory `/home/epoc/Desktop/supertuxkart-0.7.1/src'
any suggestion? Have I missed some dependencies?
ty in advance
