Установка Пехлеви на CentOS имеет проблемы зависимости

Я пытаюсь установить Сервер Зенда PHP на своем CentOS VPS, но он имеет вопросы зависимости, которые я, может казаться, не решаю.

При консалтинге с Google все, что мне говорят, - то, как установить PHP 5.2.* на CentOS. Согласно выводу php -v, Я сделал это.

PHP 5.2.8 (cli) (built: Sep 28 2009 15:37:15)

Как я могу решить эту проблему?
