|The stupid question is the question not asked|
Hi there, if you are not building a threaded perl then I don't think you linked to the relevant issue. This seems to be an issue with stat.t which is thus far unreported.
I note that on Sierra also, with an unthreaded 5.26.1, the latest Time::HiRes fails to install, as does the one installed as the Core version (1.9741) when I try to reinstall it from CPAN. Very odd. It obviously installed correctly when I built my perl(s). Given that, you might simply try building Perl 5.26.1 as your next attempt.
Hope this helps!
PS I guess CPAN Testers needs more Mac OS test reports, see App::Cpanminus::reporter.
PPS I guess this is an intermittent issue; I am able to install Time::HiRes 1.9758 successfully on 5.26.1 about half the time.
PPPS Given that it's intermittent, I would be wary of trusting Time::HiRes for accuracy. Maybe the issue is that it's just blocking your Perl install, in which case you could almost ignore it, or maybe it's critical to you, in which case you might have to install a Linux VM on your Macbook, I guess :-(
The way forward always starts with a minimal test.
