Развертывание проекта Symfony на OVH

Я пытаюсь развернуть Rest API для OVH. Я развязал его с symfony2.

все работало на моем локальном сервере, но на сервере OVH, у меня есть возможности использовать "композиторское обновление".

Fisrt я изменил ".bashrc", чтобы добавить "alias php5 = 'php.ORIG.5_4 -c/usr/local/lib/php.ini-2'"

но когда я использую "php5 composer.phar update", он возвращает:

Warning: Composer should be invoked via the CLI version of PHP, not the cgi-fcgi SAPI

я не знаю, почему buildBootstrap запускает PHP 4

Спасибо за вашу помощь
