My mistake, I got it backwards. Postfix is executing the wrapper as
mailman:mailman, the owner:group of the aliases. Mailman's wrapper is
expecting group 'nobody'.

You can't change the owner:group of the aliases or list creation won't
be able to update them. This means you need to reconfigure the wrapper
to expect group 'mailman' instead of 'nobody'. There is probably some
FreeBSD port magic way to do this, but I don't know what it is.
