bash reports "port command not found"

[Richard Rucker]

Environment:
  MacBook Pro running OS X 10.5.5
  Xcode 3.1.1 Developer Tools standard installation

1. Installed latest version of MacPorts for Leopard, version 1.6.0,  
this morning using default option. Installer reported a successful  
installation.

2. Successfully verified the .profile file using the env command.

3. Attempted to list the all available ports using
      port list

    bash reported "port: command not found"


4.  Attempted to install some dependencies for D-Rats using this  
command:
       sudo port install  <list of 4 file names>

    bash reported "port: command not found"


I checked the FAQ and archives (sorta), but didn't find this as a  
reported problem.

Please advise,
