This assume the upstream maintainers fill out the META.yml accurately
which is often not the case :( One of the tests in Module::CPANTS::Analyse
is to run the package through Module::ExtractUse and report all the things
that the maintainer forgot. Unfortunately the CPANTS website is offline
right now so I can't point to the stats showing how many Perl package
fail this test.

I've in fact got an open RFE against cpanspec[1] for it to use
Module::ExtractUse to fill in the BuildRequires properly because
its current scanning of Makefile.PL / META.yml is insufficient in
many cases.

Daniel
