One thing that seems odd there, is freeglut claiming the
problem is an "Internal error".

Had you already seen the tutorial page?

http://ruby-opengl.rubyforge.org/tutorial.html

It mentions the ability to use SDL or GLFW to obtain a
window, instead of GLUT.  Unless GLUT is a fixed 
requirement for you, maybe you could sidestep the issue
that way?
