I've never been near a zOS machine, so take all this with a grain of salt.
At first glance from your logs it looks like text is getting mixed up between ASCII and EBCDIC? For example this is not what I would expect: does not contain a Ine-Ount header. I would guess it should say does not contain a line count header.
It looks like the next version of perl will install an ascii version on zOS. https://github.com/Perl/perl5/pull/19312, https://github.com/Perl/perl5/blob/blead/README.os390
And after glancing at the readme file, maybe you could try manual module installation. It would not scale well with deep dependency trees but testing a few packages with no deps will at least tell you if things can install. https://github.com/Perl/perl5/blob/d4bd2f77c3545307502b4ad138c68247d8b1dd81/README.os390#L222
