This may be another problem, independent from what you report:  AFAIK
the poll() implementation of Mac OSX 10.4/Intel is broken, and doesn't
work for named pipes.  runit (or better daemontools' iopause()) has an
alternative implementation using select(), but this isn't chosen while
building as poll() is available, but broken.

I guess you get a prompt back after this command because of the --detach
option.

The service daemon must not background (or 'daemonize') when supervised
by runit, but must run in the foreground.  Try to remove the --detach
option.

Maybe you didn't stop the daemon you started before from the command
line, and which detached from the terminal and process tree, and now
still listens on the port.

There should be no difference, I don't know why you get no logs here.

HTH, Gerrit.
