No. Running 'perl hibye.pl' just returns me to a command prompt.

The SOAP Server script -hibye.cgi - it is trying to contact looks like

#!/usr/bin/perl -w

# -- SOAP::Lite -- guide.soaplite.com -- Copyright (C) 2001 Paul Kulch
+enko --

use SOAP::Transport::HTTP;

SOAP::Transport::HTTP::CGI
  -> dispatch_to('Demo')
  -> handle;

package Demo;

sub hi {
  return "hello, world";
}

sub bye {
  return "goodbye, cruel world";
}

sub languages {
  return ("Perl", "C", "sh");
}

so running the hibye.pl script from the command prompt should generate a message.
