There is no build_requires or recommends equivalent in MakeMaker, nor will
there be, so putting it into PREREQ_PM is the best thing to do. That's
what every MakeMaker-based module on CPAN does after all.
Its better than just dropping it and having the build fail.

*scratch head* but if you don't have the modules necessary to BUILD the
module (as opposed to those necessary to run it)... how are you going to
build it?

I'd think it would be the same as a missing requires or PREREQ_PM
requirement. CPAN shells build modules. If they don't have the
prerequisites to do that... well then things won't work. I don't know if
the CPAN shells will attempt to build the module anyway or just refuse,
but the introduction of build_requires doesn't change that behavior.
Maybe there's some confusion here as to what "build_requires" means?
Perhaps you're confusing it with the (possibly mythological) test_requires
and test_recommends?
Or maybe you're thinking its "Module::Build requires"?
