Smoker setup to compare old vs new versions?

I'd like a smoker setup which can do two things:

1) Run smokes for all the Test:: modules.
2) Compare the results between two different installed versions of Test::More.

This will allow me to smoke Test::Builder 1.5 against CPAN, see what it's
broken and try to fix it.

I've never used the CPAN smoker software before and I'm hoping somebody has a
recipe?

Thanks.
