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 a META.json to the distribution. Your buildtool should be able to autogenerate it.

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: EB, EB::Assert, EB::Config::IniFiles, EB::Expression, EB::Format, EB::Locale, EB::Report::GenBase, EB::Shell::Base, EB::Shell::DeLuxe, EB::Utils, EekBoek

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

Error: 0.20,1.002,1.003,1.006,1.007,1.008,1.009,1.010,1.012,1.013,1.014,1.016,1.019,1.021,1.025,1.026,1.029,1.03.13,1.030,1.033,1.037,1.038,1.039,1.047,1.054,1.057,1.058,1.070,1.086,1.105,2.38

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.
