The erfa package is currently not present in EPEL9. As I need it for the project of my org (together with the related Python module, which depends on this library), I did some local tests myself and the package builds out of the box with the current spec file. I wanted to submit a MR but even the branch is not there yet, so cannot do that. So could you kindly request the branch for epel9 and merge the spec file also there? Also: If I can help maintaining the package (at least on EPEL) I'd gladly do so in the future (FAS id: fedepell). Many thanks! Federico
