MacPorts 1.6 Clean install not updating/creating ~/.profile

I have a clean install of Leopard upgraded to 10.5.1 and I'm trying to install MacPorts with the 1.6 Universal Installer for Leopard. Everything gets installed, but the post install script doesn't update my .profile as noted in the Install docs. First I thought it was because I didn't have a .profile file at all, so I did a "touch .profile" in my home directory and reinstalled MacPorts. Still no updates. Is there a bug in the post install script? Or does MacPorts need more than a blank .profile file? Patrick
