Comment (by devans@…):

 gnome-session is using the existence of the environment variable
 DBUS_SESSION_BUS_ADDRESS as a test of whether a valid session dbus
 instance is running or not.  If not, then it tries to start one using
 dbus-launch which doesn't work properly on MacPorts due to our launchd
 based implementation.  This is the error message that you are seeing.

 I'm working on a more transparent fix for this, but in the meantime, you
 can work around the problem by setting DBUS_SESSION_BUS_ADDRESS by hand
 before trying to start gnome-session.  The following will do this
 correctly (assuming you have a running session dbus).
 {{{
 export DBUS_SESSION_BUS_ADDRESS="unix:path=`launchctl getenv
 DBUS_LAUNCHD_SESSION_BUS_SOCKET`"
 }}}
