Upstream released Plack-1.0036 Unfortunately this update introduced a couple dependencies on further perl-modules which are not yet available in Fedora.
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle. Changing version to '23'. (As we did not run this process for some time, it could affect also pre-Fedora 23 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
Plack's dependencies took a while to be added to Fedora so we skipped 1.0036 and went from 1.0034 to 1.0039. Still, this bug is resolved.
