Yes, the Mac version has different options. ISTR that somebody reported
that and he just left -q away. The intention of the -q option is that
nc closes the socket after a EOF instead of waiting for a few seconds.
The Mac version probably always closes the socket immediately. That
only matters if you disconnect/reconnect frequently, e.g. for hacking on
the swank backend.

You should at least see "Listening on port: 49053" somewhere.
For some more debugging output you could uncomment the body
of the log-event function in swank-mit-scheme.scm.
If you want to use the REPL you need to add something like
(define (swank:create-repl env . _)
(list "(user)" "(user)"))

The number must be very close to zero but certainly smaller than the
number of Edwin users (which is probably only a handful).
