Perl is licensed as

| This program is free software; you can redistribute it and/or modify
| it under the terms of either:
|
| 	a) the GNU General Public License as published by the Free
| 	Software Foundation; either version 1, or (at your option) any
| 	later version, or
|
| 	b) the "Artistic License" which comes with this Kit.

The perl-module.eclass offers a default LICENSE as
LICENSE="${LICENSE:-|| ( Artistic GPL-1 GPL-2 GPL-3 )}"

So if a distribution uses "the same license as Perl 5 itself" you can
just drop the LICENSE from the ebuild (as long no former eclass sets its
own LICENSE).

I've further added comments to the LICENSE in the ebuilds if it does not
use "the same terms as the Perl 5 programming language system itself"
but "or-later" group of licenses (like GPL-2+ or Artistic+...).
