title: Can't install mongoctl
body: <p>I'm working on a 13" MacBook Pro running OS X 10.8.5. I'm trying to install mongoctl with the following command:</p>
  
  <pre><code>sudo pip install mongoctl
  </code></pre>
  
  <p>But I keep getting an error when downloading and unpacking argparse1.2.1. I've tried installing mongoctl with and without sudo but the result has been the same. Here's the error I'm getting:</p>
  
  <pre><code>Downloading/unpacking argparse==1.2.1 (from dargparse-&gt;mongoctl)
  Could not find a version that satisfies the requirement argparse==1.2.1 (from dargparse-   &gt;mongoctl) (from versions: 0.1.0, 0.9.0, 0.8.0, 0.7.0, 0.6.0, 0.9.1, 0.5.0, 0.4.0, 0.2.0, 1.0, 1.0.1, 1.1, 0.3.0)
  Some externally hosted files were ignored (use --allow-external to allow).
  Cleaning up...
  No distributions matching the version for argparse==1.2.1 (from dargparse-&gt;mongoctl)
  </code></pre>
  
  <p>I installed arparse1.1 manually but don't know how to use it for this installation. Any help is much appreciated.</p>
