title: FSSM gem complaints when running a Compass watch
body: <p>I'm using Sass and Compass for CSS work but recently since I've installed RVM and the latest version of Ruby I'm getting the following notice when running a compass watch:</p>
  
  <pre><code>$ compass watch
  /Users/ian/.rvm/gems/ruby-1.9.3-p0/gems/fssm-0.2.7/lib/fssm/support.rb:40: Use RbConfig instead of obsolete and deprecated Config.
  FSSM -&gt; An optimized backend is available for this platform!
  FSSM -&gt;     gem install rb-fsevent
  </code></pre>
  
  <p>I'm running OS X Snow Leopard but I found <a href="http://frontendbook.com/fixing-sass-watch-on-os-x-lion" rel="noreferrer">this article</a> and followed the instructions there installing both fssm and rb-fsevent but that didn't make any difference.</p>
  
  <p>Can anyone suggest how I may surpress this warning each time I put a watch on my stylesheets?</p>
