Opengl games wont emerge because it can't find gl.h

[AnonNomis]

I keep getting this error when I try to emerge any opengl game

...........................................................................................

checking for GL/gl.h... no
*** Hmm, you don't seem to have OpenGL headers installed in the standard
*** location (/usr/include). I'll check in /usr/X11R6/include, since

Does anyone know whats going on? I have an Abit bp6 board and a Asus geforce2mx. I didn't use the ebuilds to install the nvidia drivers because i needed to compile them from source so that i can reduce my card to agp 1x. My board seems to have a bad agp implementation. Thanks in advance.

my glxinfo prints as follows

Thanks for your help, i skipped over that one in my search. I should be more careful next time. Well opengl-update nvidia didn't work but opengl-update xfree brought up a message that it was switching over to the xfree implementation. After that i was able to emerge tuxracer but it still wont run. I'll continue on the my search for the answer in the link you gave me. thanks again
