title: RVM Bundle Install Missing Gem Error even though gem is installed
body: <p>I'm getting the following error even though I currently do have the Bundler gem installed (it appears when I run $gem list).</p>
  
  <pre><code>ERROR: Gem bundler is not installed, run `gem install bundler` first.
  </code></pre>
  
  <p>I'm using RVM and my $PATH is as follows:</p>
  
  <pre><code>/Users/cjstingl/.rvm/gems/ruby-1.9.2-p290@rails3tutorial2ndEd/bin:

  <p>Also this is my gem env</p>

  <p>Also: Using the bundle -v command returns the same error</p>
  
  <p>I've tried imploding RVM and reinstalling which doesn't seem to work. I'm stumped and any help would be appreciated.</p>
