Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.
Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.
Error: Test-Simple-1.001014/lib/ok.pm -- Around line 40: Non-ASCII character seen before =encoding in 'åé³³'. Assuming UTF-8
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: Test::Builder::IO::Scalar, Test::Builder::Module, Test::Builder::Tester, Test::Builder::Tester::Color, Test::Simple, Test::Tester, Test::Tester::Capture, Test::Tester::CaptureRunner, Test::use::ok, ok
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
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.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
