[gentoo-dev] Re: License groups in ebuilds

2012-05-12 Thread Torsten Veller 
* Kent Fredric kentfred...@gmail.com:
 I'd welcome groups so we can have a Perl_5 group. The lions share of
 modules published on CPAN are licensed Under the same license as Perl
 5 Itself, which implies || ( GPL-2 Artistic-1 )

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+...).

That's definitely not going to work if the 'inherit' comes at the top
of the ebuild, and is severely dodgy if it doesn't...

I have to agree with Ciaran. The eclass should simply assign LICENSE
unconditionally. Ebuilds can override it if necessary.

And if an ebuild inherits two eclasses that both define LICENSE, then
it's probably better if the ebuild contains its own explicit
definition.
