title: Symfony2 : --reinstall issue
body: <p>I have been trying to install Buzz for Symfony2. I added it to the deps file, and tried to update my vendors :</p>
  
  <pre><code>php bin/vendors update
  </code></pre>
  
  <p>The command simply tells me that I've installed the standard version, and that I should try to use :</p>
  
  <pre><code>php bin/vendors install --reinstall
  </code></pre>
  
  <p>instead. Which I did.</p>
  
  <p>But then an error pops in and tells me :</p>
  
  <pre><code>Updating deps.lock
  sh:/var/www/Symfony/vendor/bundles/Sensio/Bundle/DistributionBundle/Resources/bin/build_bootstrap.php: not found
  PHP Fatal error:  Class 'Doctrine\Common\Annotations\AnnotationRegistry' not found in /var/www/Symfony/app/autoload.php on line 37
  PHP Fatal error:  Class 'Doctrine\Common\Annotations\AnnotationRegistry' not found in /var/www/Symfony/app/autoload.php on line 37
  </code></pre>
  
  <p>And then nothing works anymore, which is not surprising because my vendors folder is almost empty.</p>
  
  <p>Has anyone encountered this problem before? Any clue on how to fix it?</p>
  
  <p>Edit :</p>
  
  <p>I found out the origin of this error. I didn't have git installed, so I did :</p>
  
  <pre><code>sudo apt-get install git-core
  </code></pre>
  
  <p>Check this link for more info on that : <a href="http://comments.gmane.org/gmane.comp.php.symfony.symfony2/8239" rel="nofollow noreferrer">http://comments.gmane.org/gmane.comp.php.symfony.symfony2/8239</a></p>
  
  <p>However I'm having another error now ("Looked for namespace "buzz.client.curl", found none"). I'm making another thread for that one, as it is not the same problem (<a href="https://stackoverflow.com/questions/10649394/symfony2-no-extension-to-load-buzz">link here</a>).</p>
