CPAN Catch-22

[snax]

So I've managed to shoot myself in the foot. Earlier today I did an update of my CPAN module, via a perl -MCPAN -e shell session. This was kind of a reflex because I hadn't used CPAN for a while. That turned out OK (upgraded to v2.14 of CPAN), but ever since, any time I use perl -MCPAN -e shell and try to install or update anything, I get an annoying error:

Will not use CPAN::Meta::Requirements, need version 2.120920

Naturally that requirement is a literal specification in the v2.14 CPAN.pm module code. It's not "need >=". I have v2.125 of CPAN::Meta::Requirements.

Any clues on how best to sort this out? I grabbed source for CPAN v 2.16 but building that shows I need to upgrade other things, and I want to be able to rely on the CPAN module for managing packages. It's great when it works right :)

CPAN 2.14 uses the following to compare CPAN::Meta::Requirements version:

               'CPAN::Meta::Requirements' => [
                            sub {
                                require CPAN::Meta::Requirements;
                                unless (CPAN::Version->vge(CPAN::Meta:
+:Requirements->VERSION, 2.120920)) {
                                    for ("Will not use CPAN::Meta::Req
+uirements, need version 2.120920\n") {
                                        $CPAN::Frontend->mywarn($_);
                                        die $_;
                                    }
                                }
                            },
                           ],

where vge is defined as follows in CPAN::Version :

sub vge {
    my($self,$l,$r) = @_;
    $self->vcmp($l,$r) >= 0;
}

So it seems it's "need >=". Are you sure about the version numbers?

Thanks for pounding my head with that. Somehow I managed to get CPAN::Meta::Requirements installed in my local library at version 2.125, but it's in my main installation at 2.120351.

[root@cruncher CPAN-2.14-1ngyVR]# locate CPAN | grep Requirements.pm
/root/.cpan/build/CPAN-Meta-Requirements-2.125-0Qpk5a/blib/lib/CPAN/Me
+ta/Requirements.pm
/root/.cpan/build/CPAN-Meta-Requirements-2.125-0Qpk5a/lib/CPAN/Meta/Re
+quirements.pm
/root/perl5/lib/perl5/CPAN/Meta/Requirements.pm
/usr/local/share/perl5/CPAN/Meta/Requirements.pm

This is a problem I can sort out :)
