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”
Good to know. What I documented worked at the time, at least for me. Its been some time so maybe a few things changed. Reply approved in case I need this info in the future or someone else does. Thanks!
