Puppet error: could not find class apt

When issuing the vagrant up command, an error like this appears:

Could not find class apt for precise64.inglewood.ca.us at at /tmp/vagrant-puppet-3/manifests/default.pp:19 on node precise64.inglewood.ca.us`

      

        
        
        
      

    

Line 19 by default .pp contains:

include apt

      

        
        
        
      

    

Any ideas?

I'm on Windows 8 + Cygwin + ruby2.0
