Some error happends when I use SDL model..

[CFC]

Hi,
I've get some problem..
When I use the SDL model in my application, RDE showed the following
message..

D:/MinGW/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__': no such file to load -- sdl.so (LoadError)

How can I solve this problem?

Greetings
