Subject: How do I patch Test::Unit?

I've finally found some time to dig into one of my favorite parts of
Ruby, the Test::Unit module.  I have some ideas for how to enhance it
a bit.

First I just wanted to do a sanity check that I can make changes and
see the effects.  For some reason, no matter what I modify in my
Test::Unit source code, my changes don't seem to take effect.

For example, if I found unit.rb and added a puts statement:

at_exit do
  unless $! || Test::Unit.run?
    puts "HELLO THERE!"
    exit Test::Unit::AutoRunner.run
  end
end

but when I run my test (a simple ruby file that requires test/unit), I
don't see "HELLO THERE!".

I also tried just reopening the class right above my test class
definition:

module Test
  module Unit
    module UI
      module Console

        # Runs a Test::Unit::TestSuite on the console.
        class TestRunner
          def start
            output "Hello There!"
            setup_mediator
            attach_to_mediator
            return start_mediator
          end
        end
      end
    end
  end
end

and still nothing.

What am I doing wrong?

Oh, ruby -v reports:
ruby 1.8.6 (2007-03-13 patchlevel 0) [i686-darwin8.9.1]

Thanks
