How to determine the dbus address on OSX/MacPorts OR How to make MacPorts-dbus work with non-MacPorts qt5-install

Peeking into qt5-mac revealed that it is essential to build qt5 with configure
option "-dbus-linked" instead of "-dbus”.

Now all Qt5 applications can be started successfully and qdbusviewer.app lists
"org.freedesktop.DBus" and ":1.2" as existing and shows "Connected to D-Bus.”
also for my non-MacPorts qt5-install!
