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 =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.

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: WWW::Comic, WWW::Comic::Plugin, WWW::Comic::Plugin::Dilbert, WWW::Comic::Plugin::Goats, WWW::Comic::Plugin::MrWiggles, WWW::Comic::Plugin::UFS, WWW::Comic::Plugin::UserFriendly, WWW::Comic::Plugin::VenusEnvy, WWW::Comic::Plugin::uComics

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

Error: 1.01,1.03,1.06,1.07

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