Those ... contain the relevant bits of the diagnosis. Was there any attempt by the cpan client to satisfy the necessary prereqs? There's nothing I can do here, as the distribution does have the prereqs declared properly: https://metacpan.org/source/ETHER/Class-Load-0.24/META.json#L6 https://metacpan.org/source/ETHER/Class-Load-0.24/META.json#L137 https://metacpan.org/source/ETHER/Class-Load-0.24/Makefile.PL#L21

Unfortunately, I do not understand what you imply here, can you clarify a bit? Installation fails due to the missing prereq Data::OptList, which is in turn installed _after_ the first attempt to install Class::Load (see the first log). And is installed successfully, so it's clearly not Data::OptList's fault. So, either this is this distribution's bug or a cpan client's bug. If you say it's the latter, I'll file an issue for it too.

..which is specified correctly; however the cpan client is failing to attempt to install it. Show quoted text

Somewhere up in the cpan client's guts, yes. Perhaps it's getting confused because it's listed as both a required *and* optional prereq (albeit at different versions). When you file a ticket, please include the complete first log; it would also be helpful to link to this ticket here.
