I can build the opengl module from http://www2.giganet.net/~yoshi/ 
with Ruby mswin32 1.6.5, VC6.0, win2k like this: 


F:\otherscode\ruby\thirdparty\opengl>vcvars32.bat
Setting environment for using Microsoft Visual C++ tools.
F:\otherscode\ruby\thirdparty\opengl>ruby extconf.rb
checking for () in -lopengl32... yes
checking for () in -lglu32... yes
creating Makefile
checking for XAllowDeviceEvents() in -lXi... no
checking for () in -lglut32... yes
creating Makefile

F:\otherscode\ruby\thirdparty\opengl>nmake

Now Making glut extend module

>>> snipped about 20 warnings and build info

   Creating library glut.lib and object glut.exp
Now Making opengl extend module

>>> snipped build info

   Creating library opengl.lib and object opengl.exp

F:\otherscode\ruby\thirdparty\opengl>

Then I copied the opengl.so and glut.so to my ruby installation: 

E:\rubywin32\lib\ruby\site_ruby\1.6\i586-mswin32\

Most of the samples that come with the opengl module work.

Hope that helps,

Martin
