gnuserv no longer included in OS X High Sierra, how to replace?

[John Owens]

Advice on how to get gnuserv functionality now that the gnuserv binary is no
longer shipped with OS X High Sierra? My elisp follows. Quick scan of MacPorts
and Homebrew didn't reveal an obvious package to install that provides it.

JDO

(if window-system-not-nil
    (progn
      (autoload 'gnuserv-start "gnuserv-compat"
        "Allow this Emacs process to be a server for client processes." t)
      (gnuserv-start)
      (server-start)
      )
  )

error with gnuserv-start:
"Searching for program: No such file or directory, gnuserv"
