On macOS Mojave, the “sudo make install” part was failing for me, with the error “variable ‘PREFIX’ must be set”. Typing “env” seemed to show PREFIX set to /usr/local as per instructions so this was confusing. Then I tried “sudo env” and spotted that the sudo command didn’t have PREFIX set to anything. My solution was to invoke “sudo -i” then “export PREFIX=/usr/local” and finally “make install”
