Twig: Error Cannot redeclare class Twig_Environment

I updated vendors, and only update version twig.

 - Removing twig/twig (1.x-dev 460712d)
  - Installing twig/twig (1.x-dev 04ef7a1)
    Loading from cache

But now I get the following error:

FatalErrorException in Environment.php line 17: Error: Cannot redeclare class Twig_Environment

I cleared cache… but the error continue… I did a compare two commits… but I dont see nothing unusual…

https://github.com/twigphp/Twig/compare/460712d...04ef7a1#diff-d4416d290253c72cec40c63f54354b16
