Thanks.  I installed gems and rails.  I see you're the author of
breakpoint.  It's just beautiful!

I have to admit I'm rather disappointed in gems though.  It seems
exceedingly ugly that you have to do:

require 'rubygems'
require_gem 'rails'

to use anything that is gem-installed.

Can't seem to get breakpoint_client working yet, my client hangs but
if I telnet to the drb port, the server seems to be active.  Without
"Breakpoint.activate_drb", it works as expected from standard
input/output.

require 'rubygems'
require_gem 'rails'
require 'breakpoint'

Breakpoint.activate_drb

Thread.new do
  loop do
     begin
       breakpoint
     rescue Exception
     end
  end
end

boo="boo"
while true
  p boo
  sleep 2
end
