FOSRest gives fatal error in symfony 2

Question

i am trying to install FOSRest & FOSRestBundle

initially , i have specified following settings in the deps

[FOSRest]
    git=git://github.com/FriendsOfSymfony/FOSRest.git
    target=fos/FOS/Rest


[FOSRestBundle]
    git=git://github.com/FriendsOfSymfony/FOSRestBundle.git
    target=bundles/FOS/RestBundle

But that cause me into following error when i access http://localhost/Symfony/web/app_dev.php/

Fatal error: Declaration of FOS\\RestBundle\\Routing\\Loader\\RestRouteLoader::setResolver() must be compatible with that of Symfony\\Component\\Config\\Loader\\LoaderInterface::setResolver() in /home/logicase/public_html/Symfony/vendor/bundles/FOS/RestBundle/Routing/Loader/RestRouteLoader.php on line 29

After that i tried following setting to make to the master branch and above error remains the same

[FOSRest]
    git=git://github.com/FriendsOfSymfony/FOSRest.git
    target=fos/FOS/Rest
    version=origin/2.0

[FOSRestBundle]
    git=git://github.com/FriendsOfSymfony/FOSRestBundle.git
    target=bundles/FOS/RestBundle
    version=origin/2.0

and now when i run php ./bin/vendors install

i get following message in console.

As you can see, there is no 2.0 branch : https://github.com/FriendsOfSymfony/FOSRestBundle/branches https://github.com/FriendsOfSymfony/FOSRest/branches The installation documentation does not talk about it. You should just remove the version lines.
