It does.  Thanks for the fast turnaround.

Yes, that was the issue; thanks.

BTW, I was surprised that 'configure' did not error out when I supplied
--with-dbus (or --with-dbus=yes) on the command line.  I expect
'configure' to disable a feature (and exit with status 0) if the feature
can't be provided and wasn't explicitly requested, but I thought the
inability to provide a specifically requested feature was considered an
error.  Am I misunderstanding how 'configure' is supposed to work?
