|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 pod errors||
The documentation for this distribution contains syntactic errors in its POD. Note that this metric tests all .pl, .pm and .pod files, even if they are in t/. See 'pod_message' in the dist error view for more info.
Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.
|metayml declares perl version||
This distribution does not declare the minimum perl version in META.yml.
Excellent. Your distribution passes all the experimental metrics.
