Error: nothing provides device-mapper >= 7:1.02.96 needed by device-mapper-multipath-0.4.9-86.fc26.i686
Running rt's testsuite (Which heavily utilizes perl-CHI) doen't raise any new issue. I therefore am leaning towards considering this issue to be a problem with perl-CHI's testsuite and not to be a general problem with perl-CHI.
+1'ing to neutralize my previous vote
