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`"

Fixed in r114306. Manually setting DBUS_SESSION_BUS_ADDRESS is no longer required.
