This is using Perl 5.22.1

5.22.1 comes with makemaker 7.04_01, if the test failures bother you, replace it with the newest version available (7.16) from cpan, maybe using https://metacpan.org/pod/distribution/perl/INSTALL#Adding-extra-modules-to-the-build

1. How is this intended to work...

Don't worry about it, if you wish, report test failures to the maintainers, and then you're done

2. does that really matter here?

Don't worry about it, you're not a makemaker maintainer, or a perl5-porter, its not worth looking into

3.Do these tests expect to be using the local copy lib or the system copy? (Currently they are picking up the ones in the system library.)

Don't worry about it, tests rarely explain/document their expectations, the maintainers will know what to do....

You can always diff against the latest current version of the tests .... but http://perl5.git.perl.org/perl.git/history/HEAD:/cpan/ExtUtils-MakeMaker/t/basic.t hasn't changed in all that time
