OpenBSD 5.3 iRedmail 0.8.5 MySQL ERROR 1235 multiple triggers

I install iRedMail-0.8.5 on OpenBSD-5.3 (i386) with MySQL backend.
I watch the logs scrolling as packages are installed and configured by the setup script.
The script chokes on MySQL:

"mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
ERROR 1235 (42000) at line 341 in file: '/root/iRedMail-0.8.5/samples/iredmail.mysql': This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table'"
