DO NOT USE SU TO CREATE A NEW PROJECT

Sorry, but I cannot stress this enough, it's even mentioned in most guides. The problem is Rubygems most likely.

try running the following command.

sudo gem update --system --no-user-install.

My guess is that you originally installed this somewhere in local directory which bundler cannot access. Updating the system version and setting it as default again will hopefully get you around this.
