PerlIO is available and default in perl v5.8.0 and later. It is possible to build perl to not use PerlIO, however.

I know about the version requirement for PerlIO to be available. I am asking if there is a way, in CPAN metadata, to express that code expects $Config{useperlio} eq 'define' in the build of perl that is running the program, or do I need to consider the "PerlIO not available" case?
