This distribution doesn't create a directory and extracts its content into this directory. Instead, it creates more than one directories (some of which are probably system-specific hidden files/directories), or it spews its content into the current directory, making it really hard/annoying to remove the unpacked package.
Pack the distribution with a proper command such as "make dist" and "./Build dist", or use a distribution builder such as Dist::Zilla, Dist::Milla, Minilla.
|metayml conforms to known spec||
META.yml does not conform to any recognised META.yml Spec.
Take a look at the META.yml Spec at http://module-build.sourceforge.net/META-spec-v1.4.html (for version 1.4) or http://search.cpan.org/perldoc?CPAN::Meta::Spec (for version 2), and change your META.yml accordingly.
|manifest matches dist||
MANIFEST does not match the contents of this distribution.
Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.
|has tests in t dir||
This distribution contains either a file called 'test.pl' (the old test file) or is missing a directory called 't'. This indicates that it uses the old test mechanism or it has no test-suite.
Add tests or move tests.pl to the t/ directory!
This distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
|metayml has provides||
This distribution does not have a list of provided modules defined in META.yml.
Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build does this automatically for you.
|has separate license file||
This distribution does not have a LICENSE or LICENCE file in its root directory.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
|easily repackageable by debian||
It is easy to repackage this module by Debian.
Fix each one of the metrics this depends on.
