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 '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: Lemonldap::NG::Manager::Api::Common, Lemonldap::NG::Manager::Attributes, Lemonldap::NG::Manager::Build::Attributes, Lemonldap::NG::Manager::Build::CTrees, Lemonldap::NG::Manager::Build::PortalConstants, Lemonldap::NG::Manager::Build::Tree, Lemonldap::NG::Manager::Conf::Tests, Lemonldap::NG::Manager::Conf::Zero

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:

• Lemonldap::NG::Manager::Api::2F
• Lemonldap::NG::Manager::Build::Tree

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

Error: 2.0,2.000008,2.000010,2.000012,2.000013

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).

This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
