Windows上的ruby-opengl错误

Question

我正在尝试在Windows上使用OpenGL设置Ruby。我安装了pre-compiled ruby-opengl gem for Windows，安装完成且没有错误，但是当我尝试运行他们的nehe_lesson02.rb示例时，我收到以下错误：

c:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:60:in `require': 127: The specified procedure could not be found.   - c:/Ruby193/lib/ruby/gems/1.9.1/gems/ruby-opengl-0.60.1-x86-mswin32/lib/gl.so (LoadError)
from c:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:60:in `rescue in require'
from c:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:35:in `require'
from C:/Users/Jonathan/My Documents/Aptana Studio 3 Workspace/barberry/main.rb:8:in `<main>'

任何设法使用OpenGL设置Ruby的人是否愿意提供一些提示？
