We set mbuild_install_build_command to "./Build", which isn't working on Windows, so modules that exclusively use Module::Build can't install. Right now, that means DateTime doesn't install properly.
Created attachment 456119 [details] [diff] [review] v1 Turns out we don't need to set ./Build at all--CPAN just knows that that's the right default, and because we install a newer CPAN during install-module, it's not a problem anyway. So we can remove this on both trunk and 3.6.
