That's great. Very nice of you to follow up.

I assume you're now going to be using cpanm for installing modules from CPAN, as recommended and facilitated by perlbrew ... if so, I urge installing App::cpanminus::reporter in each Perl version and contributing your test reports to the CPAN Testers service (by simply typing cpanm-reporter after you've installed a module or a group of them). It's a great and almost effortless way to give back to the amazing infrastructure that makes working with Perl (including different Perl versions on different OSes) so easy and enjoyable.

Have fun!
