The MacPorts installation that I had on Yosemite doesn\'t work on the El Capitan since it isn\'t supported yet. I want to remove the Port installation here but I\'m not able
I just went ahead and manually removed the files (using rm):
sudo rm -rf /opt/local \
/Applications/DarwinPorts \
/Applications/MacPorts \
/Library/LaunchDaemons/org.macports.* \
/Library/Receipts/DarwinPorts*.pkg \
/Library/Receipts/MacPorts*.pkg \
/Library/StartupItems/DarwinPortsStartup \
/Library/Tcl/darwinports1.0 \
/Library/Tcl/macports1.0 \
~/.macports
It didn't seem to leave any leftovers or break anything.
One thing to note however is that mactex seems to have been installed in the same directory so that got removed as well. I didn't realize that I had that in the same directory. If you're going to repeat the same steps, keep this in mind.
