Trying to build fedabipkgdiff on RHEL9.1 fails during configure: ../../libabigail/configure --enable-rpm=yes --enable-ctf --enable-fedabipkgdiff The problem is that it is looking for the python3-mock module but that doesn't exist for RHEL9.1 even in EPEL because the package has been deprecated. $ sudo dnf info python3-mock-4.0.3-5.fc37.noarch [sudo] password for ben: Updating Subscription Management repositories.
