This message is slightly wrong in the current version of the dbus 
Portfile.  I think a more nearly correct version would be

#################################################################################################
# Startup items have been generated that will aid in
# starting ${portname} with launchd. They are disabled
# by default. Execute the following command to start the system bus,
# and to cause it to launch at startup:
#
# ${sudo}launchctl load -w ${startup_root}/Library/LaunchDaemons/[file 
tail ${plistFl}]
#
# Execute the following command for each user using dbus to cause the 
session bus to
# be started automatically when needed (you do not want sudo on this 
command):
#
# launchctl load 
${startup_root}/Library/LaunchAgents/org.freedesktop.dbus-session.plist
##################################################################################################

This assumes you installed dbus without +no_root
