Marko,

You can form the DBUS_SESSION_BUS_ADDRESS as follows:

export DBUS_SESSION_BUS_ADDRESS='unix:path='$DBUS_LAUNCHD_SESSION_BUS_SOCKET

or, in your case,

unix:path=/tmp/launch-adIO4f/unix_domain_listener

The usual way to get the session bus address programatically is to the
GDBus API provided by GIO in glib2.
In MacPorts, this has been patched to work as I have described.

See the definition of get_session_address_macports_specific (GError
**error) in
files/patch-get-launchd-dbus-session-address.diff.
