Thanks, Eleanor!  If I may suggest an additional clause
(with meaning in both the individual and group sense):

 require 'rbconfig'
   case Config::CONFIG['host_os']
   when /darwin/i
     puts "Ah, Darwin :)"
   when /linux-gnu/i
     puts "GNU/Linux - The World Community expands Consciousness"
   when /mswin|windows/i
     raise "You call that an operating system?"
   else
     raise "I haven't the foggiest"
   end
