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.

Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: DDC::Client, DDC::Client::Distributed, DDC::Concordance, DDC::Filter, DDC::Format, DDC::Format::Dumper, DDC::Format::JSON, DDC::Format::Kwic, DDC::Format::Raw, DDC::Format::Template, DDC::Format::Text, DDC::Format::YAML, DDC::Hit, DDC::HitList, DDC::Query, DDC::Query::Filter, DDC::Query::Parser, DDC::Query::yylexer, DDC::Query::yyparser, DDC::Utils

Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

Error: 0.03,0.20

Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

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