Apparently so, but it's not very clear what. You didn't answer as to what your build environment is, eg do you have any MacPorts or Homebrew packages in play. The missing files are supposed to be generated by Perl scripts, so I'm wondering if you have a broken Perl installation. Apple's standard Perl works fine for this, which is why I'm suspicious that you've got some other Perl installed that for some reason is less fine. > BTW I'm not doing anything special when compiling, just git checkout > REL_13_6, ./configure, ./make (unless I am doing something wrong there?) That's about what you need, yes. > Also the README.md makes mention of an INSTALL file that contains > instructions about prerequisites for compilation but I couldn't find it in > the repository. ?? There's no README.md in our git tree. There's no INSTALL there either, because it's a generated file. But it's just a flat text version of the same installation instructions I pointed you to before: https://www.postgresql.org/docs/13/installation.html regards, tom lane
