Or perhaps:

   require 'rubygems'
   require 'uuid'

If you ever needed a specific version of UUID, you could add a gem  
statement:

   require 'rubygems'
   gem 'uuid', '~> 1.0.4"
   require 'uuid'

The example '~> 1.0.4' will be true for all 1.0.x versions where x >=  
4, but false for all 1.1 or higher versions (this is the "Pessimistic  
Version Constraint" described at http://docs.rubygems.org/read/chapter/16#page74 
  if you want more).
