This is an unfortunately messy edge case that exposes the "cpan
distribution" <=> "perl module" disconnect we have to deal a lot with.

This is annoying, because anything that uses *other* than
filter::util::call *must* install the CPAN version.  But anything that uses
Filter::Util::Call on its own can do so from Perl itself.

Its also annoying because the "cpan distribution" that ships that module is
called "Filter" on CPAN, but "Filter-Util-Call" in perl/cpan/*
