Sorry, yes it does work that way. I've done this on another
machine running the same version of FreeBSD and the instruction
specifically specify to start the daemon this way to test the install.
(I installed from source on both machines using the same source
Every time I start this machine I start MySQL manually this way.
(Since this is a production server, it is up continuously and
it doesn't have Xwindows installed)

This is a possibility, I'll check it out.

not according to the instruction in the INSTALL-SOURCE.

I'm confused as to the class of user to assign mysql to.
It shouldn't be a user that anyone can login as, nor have
it's own home dir or login shell should it? adduser asks
and expects answers to all these questions. I don't recall
what I did on the machine that is running mysql. I guess
I could look at the password file on that machine to get
some idea.
Since the machine that won't start MySQL also has
XWindows intalled, the kdm login prompt list mysql
as a user that can log into a windowing session.
That shouldn't be necessary at all. That is why I
think the issue with the screen saver daemon
is connected to this.
