$ make -j check-world ... runs for awhile and then fails ... much excavation finds a complaint about Time::HiRes not being installed $ sudo yum install perl-Time-HiRes

Yes, looks like tests are necessary. I'd argue it's "test for broken Perl" but apparently Fedora think they should split the Perl core dist into tiny pieces.
