Call to undefined method MDB2_Error::fetchAll() in /usr/local/lib/locum/locum-server.php

Getting this error when I try to run the locum maintenence script (/usr/local/lib/locum/tools/maint.php)

Environment:
RHEL 5 86_64
PHP updated to 5.2.6

Pear:

Any ideas? Could there be a deprecated function that no longer works with PHP 5.2.6?
