title: rbenv continually generating vagrant shim
body: <p>I am using the latest vagrant with rbenv and various rubies. </p>
  
  <p>I am using the latest vagrant, which no longer uses a gem. When I execute a vagrant command I see the following error:</p>
  
  <pre><code>rbenv: vagrant: command not found
  </code></pre>
  
  <p>I have removed the old vagrant gem from all ruby environments BUT everytime I "cd" the vagrant shim is regenerated, meaning vagrant stops working until I rm the shim manually:</p>
  
  <pre><code>rm /home/{user}/.rbenv/shims/vagrant   
  </code></pre>
  
  <p>Is there a way to force rbenv to stop this behaviour?</p>
