Beside of that - perl5.x.x bundles several modules with reason:

Programms written in Perl need them and very often rely on what's bundled.
Modern author kits like Dist::Zilla prove Perl-Version (when author specifies
MIN_PERL: 5.10) which module is bundled and don't explicitly add dependencies
on that.

Nowadays it's not reasonable to distribute perl without core. What might
be sane is:

RDEPENDS_perl += "libperl perl-interpreter perl-modules"

This would allow maximum reduce for those who need and default dependency
as meant by Perl5 Porters (those who care since 5.10).

Just a side-note - catch me in IRC if wanted for a plan how to "fix" perl
after 2.1 release (maybe with 5.24 update).
