That's strange, because both python3-pyyaml (BaseOS) and rpmdevtools (AppStream) are in RHEL 9. But you are right, they are missing in UBI 9.
@tyrbiter How did you install the update? AFAICT it's not in testing yet, if you installed it manually from Koji, did you install also libtiff-tools and libtiff-devel subpackages?
Thanks for the feedback, I'll push a fixed update in a moment. The problem was in a symlink to directory change.
