@scottwittenburg I'm trying to reproduce the CI build failure locally but it seems like the Python that gets pulled down from the binary cache is broken: ```console $ /home/software/spack/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spa/linux-ubuntu18.04-x86_64/gcc-7.5.0/python-3.7.13-2rasf254brdwtgeudnsupharkvcceker/bin/python qemu-x86_64:...
