[PIPE] Problema com PDO Sqlite

Boas Malta,

Tenho um script e estou a configurar o pipe.. mas quando envio um email, ele dá-me este erro

Command died with status 255: "/var/www/pipe.php".
Command output: PHP Warning: PHP Startup: Unable to load dynamic library
'/usr/lib/php/20131226/pdo_sqlite.so' -
/usr/lib/php/20131226/pdo_sqlite.so: cannot open shared object file: No
such file or directory in Unknown on line 0 PHP Fatal error: Uncaught
exception 'PDOException' with message 'could not find driver' in
/var/www/pipe.php:66 Stack trace: #0
/var/www/pipe.php(66): PDO->__construct('sqlite:inc/xt...') #1
{main} thrown in /var/www/pipe.php on line 66

já coloquei o "pdo_sqlite.so" na pasta "20131226" e nada.. sempre o erro..

tenho o sqlite3 instalado etc..

quando coloco o "pdo_sqlite.so" na pasta "20131226" dá-me este erro

Command died with status 255: "/var/www/pipe.php".
Command output: PHP Warning: PHP Startup: Unable to load dynamic library

/usr/lib/php/20131226/pdo_sqlite.so: undefined symbol:

Não sei se já vos aconteceu isto..

Abraço ;)
