title: Struggling to install mink and behat using composer for use with symfony2
body: <p>I'm trying to install behat and mink with symfony 2.4 using composer but I can't seem to get my composer.json file to an resolve to an installable set of packages.</p>
  
  <p>I installed symfony2 using the command on  <a href="http://symfony.com/doc/current/book/installation.html">http://symfony.com/doc/current/book/installation.html</a></p>
  
  <pre><code>php composer.phar create-project symfony/framework-standard-edition /path/to/webroot/Symfony 2.4.*
  </code></pre>
  
  <p>Below is my require section of my composer.json file:</p>
  
  <pre><code>"require": {
      "php": "&gt;=5.3.3",
      "symfony/symfony": "~2.4",

  }
  </code></pre>
  
  <p>I get the following message on the screen after running composer update:</p>
