Please branch and build rxvt-unicode in epel9. If you do not wish to maintain rxvt-unicode in epel9, I would be happy to be a co-maintainer of the package. I have tested and the rawhide package is currently missing two dependencies on CentOS Stream 9 (signify and libptytty). Adding these missing dependencies the rawhide package builds without any changes. Note: The package also depends on libev-source which is already in epel9.
