Symfony 2.0 Fatal Error When Fetching Vendor Libs

[oddz]

Maybe someone knows how I can correct this so I began playing around with Symfony. Upon attempting to run the bin/vendors executable I am greeted with the below error. Any ideas?

HEAD is now at f6ec47d fixed default value
PHP Fatal error:  Class 'JMS\SecurityExtraBundle\JMSSecurityExtraBundle' not found in /Users/myname/Sites/symfony/v2.0.0/htdocs/app/AppKernel.php on line 19

I got around this by downloading the package including the vendor libs and copying and pasting the JMS package into the vendor directory.

Did you install it with composer.phar? and also clear cache.
