Not necessarily, but the code for reading the activation files is
somewhat obfuscated.  I can try to come up with a patch.  My first
thought was "misconfigured prefix", but your configure dump from earlier
showed the correct prefix of /usr.  Basically, it looks like dbus-daemon
itself isn't correctly seeing the wpa_supplicant service's system bus
activation file.
