BSD generally does a nightly scan for setuid file changes. Setgid
directories also come up on the scan when they change, which happens a
lot with mailing list archives.
I just manually un-setgid them... but I have to temporarily setgid the
root directory again when I re-install the software.
It would be nice if configure had an option with --no-setgid-dirs to
turn off this "feature".

I was confused when I installed it. I thought the program would be
setgid the group it needed to be run as, rather than checking that it
was being run from the proper group and begin setgid mailman.
It turns out that under Postfix, the program is run under GID
"daemon", but the program was checking for group "mail". So I
hard-coded it according to the instructions in the error message.
