After introduction of semantic versioning, MakeMaker emitting build-time warning

[jkeenan]

As of perl developmental release 5.41.2 (3c9d78c in the Perl core distribution), the podlators distribution now supports and itself uses semantic versioning.

    cpan/podlators - Update to version v6.0.2 (with v6.0.1 and v6.0.0)
    
    v6.0.0 - 2024-07-10
    
     - Drop support for Perl 5.10.  podlators now requires Perl 5.12 or later.
    
     - podlators now uses semantic versioning for the package and module
       versions, with a v prefix to work with Perl's packaging system.
...

ExtUtils::MakeMaker has code which compares module versions on the assumption that all such version numbers are purely numeric:

        elsif (
            $cmr
                ? !$cmr->accepts_module($prereq, $pr_version)
                : $required_version > $pr_version   ### <-- Now emits warning with semantic versioning
        ) {

This causes warnings to be emitted twice during the execution of make miniperl, make, make test_prep, and so forth.

Argument "v6.0.2" isn't numeric in numeric gt (>) at .../cpan/ExtUtils-MakeMaker/lib/ExtUtils/MakeMaker.pm line 624.

I have raised this issue in EU::MM's upstream bug tracker: Perl-Toolchain-Gang/ExtUtils-MakeMaker#472.

If upstream MakeMaker gets a fix for just this issue then PSC is fine pulling in that update last minute (even after the last dev release).

Perl-Toolchain-Gang/ExtUtils-MakeMaker#473 should fix this

Perl-Toolchain-Gang/ExtUtils-MakeMaker#473 should fix this

That fix WFM in core -- but of course it needs to be tested on older perls for CPAN release.
