How Nice :-)  Thanks.  All is forgiven, please come home.
Now lets get this puppy working.

I invoked the server like this:
  ruby ./comp_s.rb "druby://localhost:26666"

and got the following messages:
/usr/lib/ruby/site_ruby/1.6/drb/drb.rb:289:in `open': No such file or
directory - "connect(2)" (Errno::ENOENT)
	from /usr/lib/ruby/site_ruby/1.6/drb/drb.rb:289:in `initialize'
	from /usr/lib/ruby/site_ruby/1.6/drb/drb.rb:270:in `new'
	from /usr/lib/ruby/site_ruby/1.6/drb/drb.rb:270:in `open'
	from /usr/lib/ruby/site_ruby/1.6/drb/drb.rb:224:in `method_missing'
	from ./comp_s.rb:12
	from ./comp_s.rb:12:in `loop'
	from ./comp_s.rb:12

When I used my machine name or '0.0.0.0' in place of 'localhost'
I got the same messages.

Am I doing something dumb?
As mentioned before my ruby 'drb' code is version 1.3.4.2
