Sign the dist as the last step before creating the archive. Take care not to modify/regenerate dist meta files or the manifest.

Error: Old SIGNATURE detected. Please inform the module author to regenerate SIGNATURE using Module::Signature version 0.82 or newer. gpg: Signature made Thu 11 Oct 2007 06:30:14 PM JST gpg: using DSA key C289274496509C21 gpg: Can't check signature: No public key Not in MANIFEST: lib/Geo/._Gpx.pm Not in MANIFEST: t/._06.key-order.t ==> MISMATCHED content between MANIFEST and distribution files! <==

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.

If you use Mac OS X, set COPYFILE_DISABLE (for OS 10.5 and better) or COPY_EXTENDED_ATTRIBUTES_DISABLE (for OS 10.4) environmental variable to true to exclude dot underscore files from a distribution.

Error:

• t/._06.key-order.t

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: Geo::._Gpx

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.
