another way to go about this (without h2xs), would be to use ExtUtils::ModuleMaker to create the Makefile.PL and the stubs that h2xs would (without a few of the gotchas of h2xs), and make any needed changes to the Makefile.PL (and the MANIFEST file, if needed).

I've been creating a fake distro with ExtUtils::ModuleMaker lately, and have been relatively pleased with the results. I haven't completely translated the fake distro into my existing codebase yet, but that's my next step.
