title: Getting error when using command line for SASS to watch files
body: <p>I've been having problems getting Sass working from terminal in Mac OS X Mavericks on my Macbook Pro. I'm working off a brand new clean install; reformatted my hard disk, loaded Mavericks, and first thing I went into the command line to set this up.</p>
  
  <p>I did <code>sudo gem install sass</code>, then created two files on my desktop, test.css and test.scss. Then, when I try watching the files, I get an error:</p>
  
  <pre><code>$ sass --watch desktop/test.scss:desktop/test.css
  &gt;&gt;&gt; Sass is watching for changes. Press Ctrl-C to stop.
  LoadError: cannot load such file -- rb-fsevent
    Use --trace for backtrace.
  $
  </code></pre>
  
  <p>I have no idea what's going on or how to fix this, tried searching but didn't find any answers related to my problem. <code>Sass -v</code> gives me <code>Sass 3.3.2 (Maptastic Maple)</code>.</p>
