The easiest way would to be install Mailman via the port.  In particular, 
/usr/ports/mail/mailman/Makefile suggests:

CONFIGURE_ARGS= --prefix=${MAILMANDIR} --with-python=${PYTHON_CMD} \
                 --with-username=${MM_USERNAME} \
                 --with-groupname=${MM_GROUPNAME} \
                 --with-mail-gid=${MAIL_GID} --with-cgi-gid=${CGI_GID}

.include <bsd.port.pre.mk>

# The Mailman port supports a number of variables that may be tweaked at
# build time.  Getting the values of some of them right is crucial!
# Perform a "make options" to see more information on these variables.
#
MM_USERNAME?=   mailman
MM_USERID?=     91
MM_GROUPNAME?=  ${MM_USERNAME}
MM_GROUPID?=    ${MM_USERID}
MM_DIR?=        mailman
.if ${OSVERSION} >= 450000
MAIL_GID?=      mailnull
.else
MAIL_GID?=      daemon
.endif
CGI_GID?=       www
IMGDIR=         www/icons
