title: Composer install/update failing
body: <p>I'm having an issue installing a package that I created....</p>
  
  <p><a href="https://packagist.org/packages/mardy-git/redirect" rel="nofollow">https://packagist.org/packages/mardy-git/redirect</a></p>
  
  <p>As far as I can tell, everything is working fine and I should be able to install it. However when I run the composer install or update I get the following error message...</p>

  Your requirements could not be resolved to an installable set of packages.
  
  Problem 1
   - The requested package mardy-git/redirect could not be found in any version, there may be a typo in the package name.
  
  Potential causes:
   - A typo in the package name
   - The package is not available in a stable-enough version according to your minimum-stability setting
     see  for more details.

  </pre>
  
  <p>And in my composer.json file I have:</p>
  
  <pre><code>{
      "require": {
          "php": "&gt;=5.4",
          "orno/di": "1.*",
          "orno/http": "1.*",
          "orno/mvc": "dev-master",
          "orno/loader": "1.*",
          "orno/db": "1.*",
          "filp/whoops": "1.0.*",
          "symfony/console": "2.3.*@dev",
          "zendframework/zendframework": "2.1.*",
          "form-manager/form-manager": "dev-master",
          "mardy-git/hmac": "0.1.*@dev",
          "mardy-git/redirect": "dev-master"
      }
  }
  </code></pre>
  
  <p>This is a brand new package that I created this afternoon and I have not encountered problems like this before so I have no idea where to start looking for a solution. Everything else installs as expected if I remove the <code>mardy-git/redirect</code> row.</p>
  
  <p>I have tried doing a composer self-update and that didn't make any difference.</p>
  
  <p>Additional information:</p>
  
  <p><code>composer show mardy-git/redirect --verbose</code> </p>
  
  <p>...resulted in the following response:</p>
