Gnome will not start

[EBRIMA F M SAWANEH]

Hi
I have been using Virtual box to run FreeBSD and now that I have a machine
for it, I proceeded to do the installation there.
However, after doing the post installation, Gnome will not start and I
noticed the following message during the booting:
Starting dbus.
/etc/rc: WARNING:  $dbus_enable is not set properly - see rc.conf(5)

Thanks
