title: Vagrant, VirtualBox built-in or no?
body: <p>Trying to get set up with Vagrant but getting the error:</p>
  
  <pre><code>The "VBoxManage" command or one of its dependencies could not be found. 
  Please verify VirtualBox is properly installed. You can verify everything 
  is okay by running "VBoxManage --version" and verifying that the VirtualBox 
  version is outputted.
  </code></pre>
  
  <p>Just confused because the Vagrant documentation states:</p>
  
  <p>"The getting started guide will use Vagrant with VirtualBox, since it is free, available on every major platform, and <strong>built-in to Vagrant.</strong>"</p>
  
  <p>Don't want to install VirtualBox separately if its supposed to be included when I installed Vagrant. Running OSX 10.8 if it's relevant, guessing I just need to install VirtualBox? If that's the case, what do they mean in the documentation when they say it's "built-in"?</p>
