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::Handler, Lemonldap::NG::Handler::AuthBasic, Lemonldap::NG::Handler::CDA, Lemonldap::NG::Handler::CGI, Lemonldap::NG::Handler::Menu, Lemonldap::NG::Handler::Proxy, Lemonldap::NG::Handler::SecureToken, Lemonldap::NG::Handler::SharedConf, Lemonldap::NG::Handler::Simple, Lemonldap::NG::Handler::Status, Lemonldap::NG::Handler::SympaAutoLogin, Lemonldap::NG::Handler::UpdateCookie, Lemonldap::NG::Handler::Vhost, Lemonldap::NG::Handler::ZimbraPreAuth

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

Error: 1.0,1.001001,1.001002,1.002000,1.002002,1.002003,1.003000,1.003001

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.
