|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.
|no broken module install||
This distribution uses an obsolete version of Module::Install. Versions of Module::Install prior to 0.61 might not work on some systems at all. Additionally if your Makefile.PL uses the 'auto_install()' feature, you need at least version 0.64. Also, 1.04 is known to be broken.
Upgrade the bundled version of Module::Install to the most current release. Alternatively, you can switch to another build system / installer that does not suffer from this problem. (ExtUtils::MakeMaker, Module::Build both of which have their own set of problems.)
This distribution does not 'use warnings;' (or its equivalents) in all of its modules. Note that this is not about that your modules actually warn when something bad happens. It's bad if nobody can tell if a module warns or not, without reading the source code of your favorite module that actually enforces warnings. In other words, it's bad if someone feels the need to add 'use warnings' to your modules.
Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
|no invalid versions||
This distribution has .pm files with an invalid version.
Fix the version numbers so that version::is_lax($version) returns true.
These fails are not serious and don't affect your Kwalitee scores at all.
|meta yml 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 or Dist::Zilla::Plugin::MetaProvides do this automatically for you.
|has separate license file||
This distribution does not have a LICENSE or LICENCE file in its root directory.
