I just got a new Mac Pro with OS X 10.9. When I run:
I get the warning:
Warning: You have MacPorts or Fink installed: /opt/local/bin/port This can cause trouble. You don't have to uninstall them, but you may want to temporarily move them out of the way, e.g. sudo mv /opt/local ~/macports
I didn't install MacPorts or Fink, why do I get the warning?
