Oh, though logging to a dgram socket doesn't seem to work either.

I added the following line to /etc/syslog-ng.conf:

   unix-dgram("/dev/dlog");

Restarted it and checked that the socket was there.  Then I ran the following:

   > :m +System.Log.Logger
   > :m +System.Log.Handler.Syslog
   > sl <- openlog_local "/dev/dlog" "foo" [PID] USER DEBUG
   > updateGlobalLogger rootLoggerName (addHandler sl)
   > warningM "bar" "test"
   *** Exception: sendTo: protocol error (Protocol wrong type for socket)

Still the same result :-(
