Hmm. That's starting to get a bit gnarly. The Kernel module methods are
included into all objects, but they are private. As a safety feature, Mocha
currently requires that the object you are messing with must respond_to? the
method you want to mock/stub. Unfortunately for you, the standard use of
respond_to? returns false for a private method. However, I have put a
slightly nasty workaround here <http://pastie.caboo.se/11299>. See what you
think. I am loath to change the default behaviour for Mocha in this regard,
but I suppose there could be a :force => true type option.

Thanks for the kind words and good luck with the efforts at persuasion. Let
me know if I can help.
One final word of caution - I think Mocha gives you plenty of rope to hang
yourself with. I realise that you are retro-fitting tests to an existing
framework, but its far better to avoid use of the "partial mocking" aspect
of Mocha by test-driving your design in the first place.
