you already have needed options: '--enable-pdo=shared' '--with-pdo-sqlite=shared' '--with-pdo-mysql=shared' '--with-pdo-pgsql=shared'.

make sure extension_dir in your php.ini points to the place holds all the so files.

the path to php.ini should be

/usr/local/lsws/fcgi-bin/lsphp5 -i | grep "Loaded Configuration File"

also include the shared module(s) in php.ini like

extension=pdo.so;
extension=pdo_mysql.so;
...

then make a phpinfo page to verify if these modules are loaded by make a request to that page (http://test.yourdomain.com/phpinfo.php).

echo "<?php phpinfo(); ?>" > phpinfo.php
