title: Redis on Symfony2 OS X Yosemite not working
body: <p>I have got a problem with redis on Symfony2 on OS X Yosemite.
  I have installed SncRedisBundle and install redis and php55-redis with brew.
  I start the redis server with <code>redis-server</code>.</p>
  
  <p>But my symfony application returns:</p>
  
  <pre><code>500: Attempted to load class "Redis" from the global namespace. Did you forget a "use" statement?
  </code></pre>
  
  <p>Usually, I work on ubuntu with my symfony project and everything work perfectly but I want to install my project also on my mac, but I doesn't understand why it's not working on the mac.</p>
