title: Installing gosu on Mac OS X
body: <p>I'm trying to install gosu on my Mac. I used the command:</p>
  
  <pre><code>sudo gem install gosu
  </code></pre>
  
  <p>After I enter my password, I get something that says:</p>
  
  <pre><code>Building native extensions.  This could take a while...
  </code></pre>
  
  <p>However, then it comes up with this error:</p>
  
  <pre><code>ERROR: Error installing gosu:
  ERROR: Failed to build gem native extension.
  </code></pre>
  
  <p>Does anyone have any ideas to fix this? I don't know why it would be saying this.</p>
