This is a dependency of perl-XML-Feed (#1748209) The current version in Fedora builds OK for epel7 if the ExtUtils::MakeMaker version dependency is dropped and the more modern %build/%install sections are reverted to EL-7 style. I am happy to look after this branch if you don't want to maintain it for epel7.
I will make the package. https://pagure.io/releng/fedora-scm-requests/issue/19302
