If (like yours truly), you try to install MacPorts 1.6.0 from the pkg installer and the postflight script hangs or fails to complete, the following commands should do the trick (why this information isn't on front page of the MacPorts project is beyond me):
sudo curl -O http://svn.macports.org/repository/macports/branches/release_1_6/base/portmgr/dmg/postflight
chmod -x postflight
./postflight(What an exciting way to start a new blog!)
