I have ruby 1.8 installed on my windowsXP , I have also installed couple  
of gems which I need, but I get this error with every single gem I try  
to load  
(forexample rgl library in this case)

C:/rubyo/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`gem_original_r equire': no such file to load -- .rgl (LoadError) from C:/rubyo/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’ from main.rb:3

My simple main.rb file :

```auto
require 'rubygems'
require 'rgl'
puts "Hello world"
```

output of " gem env "

```auto
