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: Locale::Object, Locale::Object::Continent, Locale::Object::Country, Locale::Object::Currency, Locale::Object::DB, Locale::Object::DB::Schemata, Locale::Object::Language

Ask the owner of the distribution (the one who released it first, or the one who is designated in x_authority) to give you a (co-)maintainer's permission.

Error:

• Locale::Object
• Locale::Object::Continent
• Locale::Object::Country
• Locale::Object::Currency
• Locale::Object::DB
• Locale::Object::DB::Schemata
• Locale::Object::Language

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

Error: 0.1,0.2,0.21,0.31

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.
