title: Gem install hangs indefinitely
body: <p>Background: I'm a designer that works well with HTML, CSS, and JS. But when it comes to setting up my environment is where I fall short.</p>
  
  <p>I recently purchased a home computer. I want to set up <a href="http://middlemanapp.com/getting-started/" rel="noreferrer">Middleman</a> to use in a project. I already installed rvm and all its requirements. I am on ruby-2.0.0-p0, which from what I understand is the latest stable release.</p>
  
  <p>When I attempt to install Middleman, or any other gem for that matter, nothing happens. The cursor just moves to the next line. <img src="https://i.stack.imgur.com/iYtLz.png" alt="Screenshot"></p>
  
  <p>Some guidance, or troubleshooting steps, would be greatly appreciated!</p>
  
  <p>Thank you, </p>
