Mailman's CGI scripts must run as group 'mailman' (or whatever is
specified as the mailman group). Therefore, the wrappers are in the
mailman group and SETGID.

For security reasons (to prevent anyone from running a wrapper), the
wrappers check to be sure the original group of the caller was the
expected group. It's this expected GID that is set via the
--with-cgi-gid option to configure, but as you note, you are
installing a packaged Mailman (a FreeBSD port) so this really doesn't
apply, at least if the packager set it up right.
