The error message is wrong.

Actually it's correct, just a bit unclear. UPDATING includes the
complete procedure you should always follow when building world. It
includes a 'mergemaster -p' step, precisely for the purpose of adding
new users and groups when they appear.
Dear Kris
I have a few questions related to this error message
ERROR: Required audit group is missing, see /usr/src/UPDATING

I know that updating requires the mergemaster steps because I read the
handbook. But I don't understand why this message tells me to look
in that file, when there's nothing about that in it.

Is /usr/src/UPDATING synonymous to 'the correct updating procedure'?

By definition, yes.

Or is there a file which describes how I can manually insert needed
groups and users when I mess up mergemaster runs?

The documented procedure in `/usr/src/UPDATING', as Kris has already
mentioned includes a run of mergemaster with the -p option. Copying
from my CURRENT's version of `UPDATING':

% To rebuild everything and install it on the current system.

Read these instructions. Then read them again. Then throw away that
script and start over :)

And finally, is it really necessary to reboot after 'mergemaster -p'?

No. `UPDATING' mentions running `mergemaster -p' *AFTER* rebooting into
single user mode, not *BEFORE*.

Lately I've skipped that step with no adverse side-effects, saves me one
reboot :-)

You'll start booting into single user mode again, when you try to run
`make installworld' with an old kernel and have it blow up, leaving you
with a half installed base system and a lot of `interesting' work in
front of you. Or when you install everything without a reboot, replace
your old working userland and then find out that your new kernel is
unbootable and your new userland is unusable without a new kernel.

Booting into single user mode guarantees that you have verified at least
once that the new kernel works. There's a very good reason why this is
recommended :)
