Error when update to Symfony 2.4.1

Hi.
I get an error when I try update to Symfony 2.4.1. I copied the line "symfony/symfony": "~2.4", and I pasted to the original composer.json. But when i pushed to my openshift repo, I get this error:

a typo in the package name.

The problem is the ICU library http://symfony.com/doc/current/components/intl.html#installation

Add to your composer.json:

 "symfony/icu": "1.0.*",

and update your composer.lock file symfony/icu

php composer.phar update 

then commit and push to deploy

Note: your composer.json should look like these:

 "require": {
        "php": ">=5.3.3",
        "symfony/symfony": "~2.4",
        "symfony/icu": "1.0.*",
        "doctrine/orm": "~2.2,>=2.2.3",
        "doctrine/doctrine-bundle": "~1.2",
        "twig/extensions": "~1.0",
        "symfony/assetic-bundle": "~2.3",
        "symfony/swiftmailer-bundle": "~2.3",
        "symfony/monolog-bundle": "~2.4",
        "sensio/distribution-bundle": "~2.3",
        "sensio/framework-extra-bundle": "~3.0",
        "sensio/generator-bundle": "~2.3",
        "incenteev/composer-parameter-handler": "~2.0"
    },

If your cartridge is PHP 5.4, you can use
´´´
"symfony/icu": "1.1.*",
´´´
(remember to update your composer dependencies.
