META.yml does not conform to any recognised META.yml Spec.

Take a look at the META.yml Spec at http://module-build.sourceforge.net/META-spec-current.html and change your META.yml accordingly.

The documentation for this distribution contains syntactic errors in its POD. Note that this metric tests all .pl, .pm and .pod files, even if they are in t/. See 'pod_message' in the dist error view for more info.

Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.

META.yml does not conform to the Current META.yml Spec (1.4).

Take a look at the META.yml Spec at http://module-build.sourceforge.net/META-spec-current.html and change your META.yml accordingly.

This distribution does not declare the minimum perl version in META.yml.

If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.

This distribution does not 'use warnings;' in all of its modules.

Add 'use warnings' to all modules. (This will require perl > 5.6)

This distribution does not have a LICENSE or LICENCE file in its root directory.

This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
