 i execute
 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

 and try to reinstall
 but it shows a window stating:
 The installation failed
 The installer encountered an error that caused the installation to fail.
 Contact the software manufacturer for assistance.
