title: Bundler can't seem to find correct Ruby through Rbenv
body: <p>For years I used RVM as my Ruby version manager, but I want to switch to rbenv for its simplicity. However I'm finding some strange problems deploying. Here's where it seems to go wrong:</p>
  
  <pre><code># env RBENV_ROOT=\"/home/deploy/.rbenv\" PATH=\"/home/deploy/.rbenv/shims:/home/deploy/.rbenv/bin:$PATH\"  /home/deploy/.rbenv/bin/rbenv exec bundle install --gemfile /domains/myapp.com/releases/20140119013611/Gemfile --path /domains/myapp.com/shared/bundle --deployment --without development test
  
  &gt; rbenv: bundle: command not found
  
  &gt; The `bundle' command exists in these Ruby versions:
  &gt; 2.0.0-p353
  </code></pre>
  
  <p>Okay, so I specify the rbenv version I want -- </p>
  
  <pre><code># env RBENV_ROOT=\"/home/deploy/.rbenv\" PATH=\"/home/deploy/.rbenv/shims:/home/deploy/.rbenv/bin:$PATH\" RBENV_VERSION=\"2.0.0-p353\" /home/deploy/.rbenv/bin/rbenv exec bundle install --gemfile /domains/myapp.com/releases/20140119013611/Gemfile --path /domains/myapp.com/shared/bundle --deployment --without development test
  &gt; rbenv: version `"2.0.0-p353"' is not installed
  </code></pre>
  
  <p>Huh. That's weird.</p>
  
  <pre><code># rbenv versions
  &gt; system
  &gt; * 2.0.0-p353 (set by /home/deploy/.rbenv/version)
  </code></pre>
  
  <p>Any idea where I'm going wrong? The <code>bundle install</code> command appears to think that <code>2.0.0-p353</code> is absent, but <code>rbenv versions</code> shows it. What might be up?</p>
