title: Permission denied when running script/server
body: <p>I just cloned the <a href="http://github.com/appoxy/mini_fb_demo" rel="noreferrer">mini_fb_demo</a> from Github, went into the directory and ran <code>script/server</code>, and got this error:</p>
  
  <pre><code>-bash: script/server: Permission denied
  </code></pre>
  
  <p>I've been using script/server like this for other projects for awhile, and this has never happened. What is causing this? Thanks for reading.</p>
