В FreeBSD на самом деле проще самому собрать Openfire, чем использовать сборку из портов.

Устанавливаем JDK согласно данному топику.

Скачиваем архив с исходниками openfire_src_3_7_0 отсюда.

Распаковываем. Переходим в директорию build. Выполняем:

ant openfire
ant plugins

Все будет собрано в директории target. Переносим ее сдержимое, например, в /opt/openfire.

Создаем скрипт для запуска /etc/rc.d/openfire (выставляем правильные права, прописываем openfire_enable=«YES» в /etc/rc.conf):

#!/bin/sh

# PROVIDE: openfire
# REQUIRE: NETWORKING SERVERS
# BEFORE: DAEMON
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf.local or /etc/rc.conf
# to enable this service:
#
# openfire_enable (bool):   Set to NO by default.
#               Set it to YES to enable openfire.
# openfire_user (username): Set to openfire by default.
#               Set it to required username.
# openfire_group (group):   Set to openfire by default.
#               Set it to required group.
# openfire_libdir (path):   Set to /usr/local/share/java/classes by default.
#               Set it to java classes directory.
# openfire_home (path):     Set to /usr/local/share/java/openfire by default.
#               Set it to java home directory.
# openfire_javargs (args):  Set to -Xmx256M by default.
#               See java -h for available arguments.

Создаем пользователя openfire входящего в группу openfire:

pw groupadd openfire
pw useradd openfire -d /opt/openfire -s /usr/sbin/nologin -G openfire

Выставляем права:

chown -R openfire : openfire /opt/openfire/

Потом можно расставить права более утонченно.
