Subject: Dependency problem: does not install on fresh 5.26.0 installation
I have just installed 5.26.0 with the defaults for everything. ‘test Class::Load’ in the CPAN shell fails, apparently because a required dependency (Data::OptList) is listed as optional, so things get processed the wrong order. What I think are relevant parts of the build log are as follows: $ cpan5.26.0 Loading internal null logger. Install Log::Log4perl for logging messages There seems to be running another CPAN process (pid 16650). Contacting... Other job is running. Shall I try to run in downgraded mode? (Y/n) [y] Running in downgraded mode (experimental). Please report if something unexpected happens cpan shell -- CPAN exploration and modules installation (v2.18) Enter 'h' for help.

Message body is not shown because it is too large.

I think the issue is that Data::OptList is listed in both requires and recommends. The required version is version 0 and the recommends is for 0.110. I'd argue that this is a bug in the CPAN shell, but it probably makes sense to just require the 0.110 version.

This is most definitely a CPAN bug. I'll move this ticket there. (I'll also update the prereqs in metadata so we don't hit this problem again, in the meantime.)
Having reproduced this in 2.18 we've been unable to reproduce in 2.20. This appears to be fixed now.

Indeed, this looks like a duplicate of #121914 which was fixed in 2.19. I'll mark this one as fixed, too.
Marking as resolved, since release 2.22 is out and not a trial. Thanks!
