Bug#560626: t/99_pmv.t test failure with new Perl::MinimumVersion 1.22

[Salvatore Bonaccorso]

Hi

First of all, I agree that this is a failure of build when activating
author tests. We in Debian Perl Group try to activate any test which is
possible to quarantee best quality. During such a rebuild of package for
Module::Install it fails to build. There was an update in
Perl::MinimumVersion:

1.22 Wed  25 Nov 2009
        - Negative length in 'splice' requires perl 5.5 (Alexandr Ciornii)
        - 'mkdir' with one argument requires perl 5.6 (Alexandr Ciornii)
        - 'substr' will not be checked if it is a method name (Alexandr Ciornii)
        - better tests and fix for 3-arg 'open' (Alexandr Ciornii)

1.21 Tue  24 Nov 2009
        - Add 'bytes' to 5.6 pragma (Alexandr Ciornii)
        - Add support for "version numbers" like "v1.1.1" (Alexandr Ciornii)
        - Reimplement _three_argument_open, more tests (Alexandr Ciornii)
          Now check for 3-arg open is working.
        - Check 4-arg substr that requires perl 5.5 (Alexandr Ciornii)
        - Postfix foreach requires perl 5.004.05 (Alexandr Ciornii)
        - Scalar::Util::weaken requires perl 5.006 (Alexandr Ciornii)
        - P::MV itself found imcompatibility in 02_main.t with 5.5 (Alexandr Ciornii)

Now Module::Install fails with:

The full Bugreport is located at http://bugs.debian.org/560626

The problem is that in the tests there are used syntax not matching the
required version in META.yml.

Many thanks for considering looking into it,
Bests
