[Module::Build] How to I specify in META.yml a package needs a C compiler?

[R. B. <ro...@pa...>]

dlisp options from Kobe's CPAN search I think use META.yml and
META.yml is set via Module::Build. I have a package that requires a C
compiler, but dlisp/META.ymal doesn't show that. How do I specify that
(e.g. in Build.PL)?

Thanks.
