you can use them directly with ruby/dl


   harp:~/build/ruby-1.8.4/ext/dl/sample > cat a.rb
   require "dl/import"
   require "dl/struct"

   module LIBC
     extend DL::Importable

     begin
       dlload "libc.so.6"
     rescue
       dlload "libc.so.5"
     end

     extern "int atoi(char*)"
   end

   p LIBC.atoi("42")


   harp:~/build/ruby-1.8.4/ext/dl/sample > ruby a.rb
   42

dl is included with ruby
