I'm very ignorant of the building of rpms and spec files but should R have a requirement (both build and run) tzdata? I was exploring the spec file and couldn't see it mentioned but, AFAICT, it is required unless you are using the optional bundled data base. My curiosity was triggered after reading the recent thread on devel (https://lists.fedoraproject.org/archives/list/devel at lists.fedoraproject.org/thread/CRUWIEHISRLYQ5ZLPFSAFJPRTDQQLBO2/) and then seeing that the related change request was recently approved (https://pagure.io/fesco/issue/3031). Apologies for the noise if I'm misunderstanding how things work. Cheers Tim
