title: Intern: The environment you requested was unavailable
body: <p>We are using <strong>Intern</strong> to test our application. We have three different Intern configuration files which we use to target either a local instance of <strong>Selenium</strong>, an instance running on a local <strong>virtual machine</strong>, or <strong>Sauce Labs</strong>.</p>
  
  <p>Intern runs tests against Firefox on both the local instance and the virtual machine without error. However, when I add Chrome to the list of browsers I would like to be tested against, on both the local and virtual machine instance, I get an error indicating: "<em>The environment you requested was unavailable</em>". I know that the required browser is available in both locations, and in fact I know that this process has worked in the past. What could have changed and what do I need to configure to make Intern and or Selenium see Chrome again?</p>
  
  <p>I'm working on a machine running Windows 7 and the VM I have installed runs up an Ubuntu image, carefully installing Firefox, Chrome and PhantomJS along the way.</p>
  
  <p>When running against a local instance of Selenium we are using the following configurations:</p>
  
  <pre><code>capabilities: {
      'selenium-version': '2.39.0'
  },
  
  environments: [
      { browserName: 'chrome' },
      { browserName: 'firefox' }
  ]
  </code></pre>
  
  <p>When running against Selenium on an Ubuntu VM we are using the following configurations:</p>
