Can someone tell me what I'm missing please?

I am trying to get PEAR Mail_Queue working on a hosted server. I've
followed the tutorial steps though but the final command to ad mail
to the queue fails with:

PHP Fatal error: Call to a member function on a non-object in /home/
prescrib/pear/pear/php/Mail/Queue/Container/db.php on line 189

This line is:

$id = $this->db->nextId($this->sequence);

What am I doing wrong?

Thanks in advance,
Matt
