Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.
Error: POEIKC-Plugin-IRC-0.00_02/lib/POEIKC/Plugin/IRC.pm -- Around line 338: L<> starts or ends with whitespace
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
Error: POEIKC::Plugin::IRC, POEIKC::Plugin::IRC::ClientLite
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
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).
