Thanks for taking the time to report this bug and helping to make Ubuntu better.
It looks like the error you have experienced is related to a conflict between the packaged installation of puppet and a custom manual installation of puppet you have in /usr/local/lib/site_ruby/1.8/puppet.
Thus this problem appears to be on your system and not a bug in Ubuntu. Accordingly I am marking this bug as Invalid in Ubuntu.
If I am mistaken, please do explain and change the status back to New.
