Subject: Problems using ruby and opengl

So I just recently started using ruby and I love it.  I am also taking
a computer graphics course and I am using C and C++ to use OpenGL.  I
did a little searching, and it seems that ruby can do OpenGL too, but
I've had some problems...

I get this error every time I try to call Glut.glutCreateWindow :

freeglut  ERROR:  Internal error <FBConfig with necessary capabilities
not found> in function fgOpenWindow
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  4 (X_DestroyWindow)
  Resource id in failed request:  0x0
  Serial number of failed request:  25
  Current serial number in output stream:  28

I used both my code and example code (though I haven't had much luck
finding any).  The ruby-opengl page is surprisingly unhelpful, with
very little information and tutorials.

Also, I've noticed that the sample programs I found haven't needed
these two lines:

require 'rubygems'
gem 'ruby-opengl'

I'm not entirely sure what's up.
