Problem running Ruby 2 + Rails 4 on Ubuntu 12.04 TLS

Hello

I'm trying to use Ruby 2 and Rails 4 on production but there seems to be a problem with the version of Rubygems that comes with Ruby 2.0.0-p247.

I installed Ruby 2.0.0-p247 and Rails 4.0.0 on a fresh Ubuntu 12.04 TLS server VM

vagrant@dev:~$ gem -v
2.0.3
vagrant@dev:~$ bundle -v
