Thank you for everyone’s responses thus far.
So, to give a bit more context:
My MacPorts dbus install puts the system socket at /opt/local/var/run/dbus/system_bus_socket. That path is hard-coded into libdbus but doesn’t appear to be available to any other client library.
Is this a bug in the MacPorts installation, then?
