Помогите emerge -av dev-lang/php не видит опцию sharedext

Здравстуйте, помогите разобраться с проблемой, пытаюсь установить php 5.3 с опцией sharedext, но ничего не выходит.
Прописываю ее в /etc/make.conf в /etc/portage/package.use или же просто в консоле
Однако это опция не подхватывается см вывод в консоле:
USE="sharedext" emerge -av dev-lang/php

Соответственно php устанавливается без файлов .so , папка /etc/php/apache2-php5.3/ext/ пустая

см вывод
