First off, get the port with portmanager:
[root@dev ~]# portmanager www/phpbb
This will now install a couple of ports that phpBB depends on:
Now, so that you can access to phpBB you must create an alias (because phpBB installs it in So put this in your httpd.conf file:
Alias /phpbb /usr/local/www/phpBB2/
<Directory "/usr/local/www/phpBB2/">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
