I'm assuming you've read README.ext already?
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/branches/RUBY/README.EXT? 
view=markup

Have you investigated using the inline library?  It might make more  
sense if you just need a few functions.

Using C from Ruby is a bit more complex than just regular ruby  
programming, but hopefully those links can get you started.
