Mysql errors on upgrade to 9.14.509

Running debian woody with mysql 3.23.49 and php4 4.1.2 and apache 1.3.26

Upgrading from 006 to 509, I get the following mysql errors after updating
the header.inc.php file:

I logged in to mysql as phpgroupware and tried some of the commands by
hand, with the same errors resulting. Could I perhaps grant some
priviledges to phpgroupware and try again? I have never done any manual
setup/modifications to the phpgroupware tables, and have only used the
install scripts.
Logging in as setup admin, everything seems fine. I haven't tried
upgrading applications yet. Logging in as a user, I get the following:
Database error: Invalid SQL: UPDATE phpgw_async SET
next=0,times='a:0:{}',method='none',data='a:3:{s:6:\"run_by\";s:8:\"fallback\";s:5:\"start\";i:1063467334;s:3:\"end\";i:0;}',account_id=0
WHERE id='##last-check-run##'MySQL Error: 1054 (Unknown column 'account_id' in 
'field list')
