Its been over a year since I installed Macports for Ruby. I want to uninstall but I can't remember if I was using for anything crucial. Can I get a nice list of ports that was directly installed?
Macports documents how to uninstall it
Uninstall the ports by
sudo port -fp uninstall installed
Then remove all the files
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
