How is ruby-debug Suppose To Work?

I am referring to

http://blogs.sun.com/martink/entry/remote_debugging_debug_whatever_ruby

I fixed the initial problems. Renamed ruby-debug-ide to ruby-debug and commented out run_init_script method (saw a posting mentioning this). Using the following code I was expecting execution to suspend at the debugger(7000) line when I do a >ruby main.rb. I would then attach the Netbeans remote debugger. Nothing suspends. I can't find any info on the net on this. What is suppose to happen? I am running everything on the same machine.

main.rb file

require 'rubygems'
require 'ruby-debug'

def test_debug
puts "Hello World"
debugger(7000) # 7000 being a port
puts "Hello World2"
end

test_debug
