Well, between watching cartoons with my son, fixing dinner, and getting him into the bath, it took a couple hours to get MySQL and MovableType up and running on my server. Woo hoo!
First, be sure you're running Mac OS X Server 10.2.x. Otherwise, these instructions won't help you. :)
Then, get MySQL running.
Download the latest MovableType.
To setup MySQL for MovableType, do the following (after getting MySQL running per the Apple KB article above):
# mysql --user=root --password=root_mysql_password
> create database mtdb
> grant all privileges on mtdb.* to mt@localhost
> identified by 'mt_password' with grant option;
> quit
Finally, follow the instructions at:

Note that any directory to which MT will be writing a file needs to either have 777 permissions, or have owner and/or group of "www" with write permission.
