--- Comment #2 from Paul Howarth paul@city-fan.org --- The perl-JSON-XS package can be found in the Code Ready Builder (RHEL) / PowerTools (clones) repository. Many EPEL dependencies, particularly for perl packages, can be found there.
You'll need to enable that repository to get the package. There has been some discussion recently about auto-enabling this repository when installing epel-release: https://www.mail-archive.com/epel-devel@lists.fedoraproject.org/msg09770.htm...
