Ouch, ok. But actually, I'm not quite sure anymore whether the patch is
really required. I ran into the "readlink -f" problem and thought that
it occurred due to the ancient version of bash on macOS, but as a I now
know, readlink is a separate program and not a bash built-in, so it's a
different issue... thus let's skip this patch here for now until we hit
a real issue with bash again.
