help!

building with MAILMAN_MAILGROUP?= nobody as said in the Makefile when 
using postfix gets me a similar error (gids swapped, that is):

blackjack-a$ /usr/pkg/lib/mailman/mail/mailman bounces mailman@riscworks.net
Group mismatch error.  Mailman expected the mail
wrapper script to be executed as group "nobody", but
the system's mail server executed the mail script as
group "mailman".  Try tweaking the mail server to run the
script as group "nobody", or re-run configure,
providing the command line option `--with-mail-gid=mailman'.

while building with MAILMAN_MAILGROUP?= maildrop (postfix runs as:

postconf | grep gid
setgid_group = maildrop)

yields

blackjack-a# /usr/pkg/lib/mailman/mail/mailman post mailman@riscworks.net
Group mismatch error.  Mailman expected the mail
wrapper script to be executed as group "maildrop", but
the system's mail server executed the mail script as
group "wheel".  Try tweaking the mail server to run the
script as group "maildrop", or re-run configure,
providing the command line option `--with-mail-gid=wheel'.

regardless of the group i build mailman with, it just doesn't run.

may virtual_gid_maps be worth a look?
