Subject: How to breakpoint ruby code ?

Hello, I would like to know how I can have my ruby code stopped and an 
irb invoqued which would allow me to have full access to the current 
context.

I've tried this :

require 'rubygems'
require_gem 'ruby-breakpoint'

h2 = Hash.new
breakpoint

Two things are wrong :
1) after breakpoint the context is lost, and typing h2 gives
undefined local variable or method `h2' for #<Object:0xb7f8d9fc 
@__bp_file="./test.rb", @__bp_line=21>

2) require_gem puts a warning (use gem instead), and using gem 
'ruby-breakpoint' makes breakpoint command to be unknown :
undefined local variable or method `breakpoint' for main:Object (NameError)



Seems I'm on the very wrong way as I presume that 
debugging/breakpointing is certainly a very common task with Ruby.


Thanks



Note : In fact, I would like something similar to the Rails console for 
use with non Rails ruby code.
