Where is DB.php ? Suse 10.0.

Hi, I'm trying to install PHP application and it complains : robi:/usr/src/AMP # ./install_amp Checking for PEAR DB..FAILED [FATAL] PEAR must be installed (requires DB.php). Include path: /usr/share/php I've installed php4-pear and I'm searching for file DB.php and it isn't there. Does anyone know in what package is this file included or is it missing from Suse rpm's ? Thanks in advance, regards, Rob.
