That means that when rails did require ‘rubygems’ nothing good happen.  
What happens if you stick  
require ‘rubygems’  
into an irb session ?

Just resolved that issue…Download the new RubyGems, untar and run  
sudo ruby setup.rb (from the rubygems folder you just created)  
you may have to reinstall the rails gem as well  
sudo gem install -v=2.1.0 rails
