Problem s PHP

Ahojte, mam nainstalovany Apache,Mysql, PHP, lenze mam po nedavnom "vypadku" elektriny problem ze mi nevie nacitat kniznicu php_pdo.so, v adresary modulov neexistuje a nenajdem ju ani v celom systeme ... po preinstalaci PHP sa nic zavratne nepohlo.

Pouzivam system Arch Linux,

pri instalaci pdo.so s pecl install pdo napíše tuto chybu
