Bug#592471: libcarp-clan-perl: Carp::Clan 6.02 has no licenses

[Vincent Lefevre]

Package: libcarp-clan-perl
Version: 6.02-1
Severity: serious
Tags: upstream fixed-upstream
Justification: Policy 2.3

Upstream Carp-Clan 6.02 has no licenses. Its META.yml file contains:

license:             ~

and the README file doesn't say anything about the license either.
I doubt that the fact the author distributed the Artistic.txt and
GNU_GPL.txt files is sufficient from a legal point of view (note that
for some software, such license files apply only to some part of the
software). Without a license for the whole module distribution, one
can look at what individual files say.

lib/Carp/Clan.pm says:

## This module is free software and can
## be used, modified and redistributed
## under the same terms as Perl itself.

but lib/Carp/Clan.pod says nothing about the license, making at least
the documentation non-free.

There are also possible licensing issues with the test files, which
are silent too.

Anyway this licensing problem is fixed in upstream Carp-Clan 6.04:

Version 6.04  24.10.2009
 + Solved RT ticket #50796 (inform type of license)
 + Made the test suite compatible with Perl versions < v5.6.0

Version 6.03  18.10.2009
 + Re-release to resolve confusion in CPAN caused by intermediate release
   of Carp::Clan 5.4 (backport of bugfix #50560 below for Perls < v5.6.0)
