Composer dependency error when installing Sylius Bundles into Symfony 2.4

I have problems installing Sylius Bundles (namely SyliusProductBundle) into a fresh Symfony 2.4 install

rm -rf * .gitignore .travis.yml
composer create-project symfony/framework-standard-edition ./ 2.4.* --prefer-dist

Symfony install goes through with no errors: Clearing the cache for the dev environment with debug true Installing assets using the hard copy option Installing assets for Symfony\Bundle\FrameworkBundle into web/bundles/framework Installing assets for Acme\DemoBundle into web/bundles/acmedemo Installing assets for Sensio\Bundle\DistributionBundle into web/bundles/sensiodistribution

On we go, next to installing the bundles - let's first use the way it's described in the docs :

composer require "sylius/product-bundle":"1.0.*@dev"

fails:

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for sylius/product-bundle 1.0.*@dev -> satisfiable by sylius/product-bundle[1.0.x-dev].
    - sylius/product-bundle 1.0.x-dev requires sylius/resource-bundle 1.0.*@dev -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

Read <http://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

Installation failed, reverting ./composer.json to its original content.

I've tried several things (including an install of Doctrine Bundle 1.3 which led to even more errors referring to some Class missing and thus failing to clear the cache):

2.2751   19015200   9. require('-ABSOLUTE PATH HERE-vendor/doctrine/doctrine-bundle/Doctrine/Bundle/DoctrineBundle/Command/Proxy/CollectionRegionDoctrineCommand.php') -ABSOLUTE PATH HERE-vendor/symfony/symfony/src/Symfony/Component/Debug/DebugClassLoader.php:120

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception



  [RuntimeException]
  An error occurred when executing the "'cache:clear --no-warmup'" command.

I've read that it might be a problem with my configuration which is why I made sure that the system timezone is set correctly which it definetely is. My set up reads as follows: Mac OS X 10.9 MAMP free with PHP 5.4.10, installed Extensions include XDebug and XCache I'm out of luck on this one and would appreciate a solution.

Thanks!

As suggested, my composer.json
