Things get worse. I supposedly installed perl using "dnf install perl" in Fedora 31, which seemed to work OK. However, I now have no command "perl" in any of my "bin"s and no paths in @INC. I looked for a simple perl tarball, like I used many years ago, but can't find one, only "ActivePerl-5.28.1.0000-x86_64-linux-glibc-2.12-f7fd6fde.tar.gz".
