title: Vagrant problem in OSX (Ruby Gem deprecated warnings)
body: <p>I'm trying to get Vagrant set up on OSX to manage my VMs.  I have followed the instructions on the site, however when I get to 'vagrant up' I get the following output (it sets up the VM but then automatically destroys it) - is this related to the Vagrant/Virtual Box versions?:</p>
