glClearColor not found on some machine, some CL system

[Rujia Liu]

I've tested on 3 other machines. 2 with OpenGL 2.1 and 2 with OpenGL 4.3

It seems that OpenGL 2.1 machines can run SBCL executable while OpenGL 4.3
cannot. But on all machines ccl executable cannot run.

I don't think glClearColor has changed between OpenGL 2.1 and OpenGL 4.3,
from the latest reference:

http://www.opengl.org/sdk/docs/man/xhtml/glClearColor.xml

So I'm confused. Any help would be appreciated. Thanks!!!
