It seems macports is installed on your mac, this can cause issues\\n
the recommended path is to use homebrew. Since this is potentially\\n
destructive, I will not attempt to remove port myself! However\\n
here is how to do it:\\n
\\n
sudo port -fp uninstall installed\\n
sudo rm -rf
    /opt/local
    /Applications/DarwinPorts
    /Applications/MacPorts
    /Library/LaunchDaemons/org.macports.*

    /Library/StartupItems/DarwinPortsStartup
    /Library/Tcl/darwinports1.0
    /Library/Tcl/macports1.0
