Seems a good tool but unfortunately didn't worked... The 'debugger' 
statement producing no effect at all.

But, I re-installed ruby-breakpoint and thanks to this article 
(http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/213319) I 
have been able to breakpoint again in the code by adding
require 'breakpoint185'
after
require 'breakpoint'

Without that the first require I get a message "Breakpoints are not 
currently working with Ruby 1.8.5"

So, it seems to work - And my last question is :
h1 = Hash.new
@h2 = Hash.new
breakpoint

under debugger, @h2 exist but h1 does not. Quite annoying to loose the 
local vars - Is it a normal behaviour for a ruby debugger ? Should have 
worked like that with ruby 1.8.4 ?
