|buildtool not executable||
The build tool (Build.PL/Makefile.PL) is executable. This is bad because you should specify which perl you want to use while installing.
Change the permissions of Build.PL/Makefile.PL to not-executable.
This distribution has .pm files with inconsistent versions.
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
These fails are not serious and don't affect your Kwalitee scores at all.
|metayml has provides||
This distribution does not have a list of provided modules defined in META.yml.
|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.
