Error: Unable to open port: invalid command name "ui_channels"

[estrnod@…]

I am running OS X 10.4.11 on Powerbook G4. I had the same error above with 'port upgrade outdated' on MacPorts 1.7.0 (having done a successful selfupdate but 'port upgrade outdated' failed. I installed (upgraded to) 1.8.2 over 1.7.0 from a dmg, did another selfupdate, then tried 'port upgrade outdated' but it still failed with the error in the summary above. So I uninstalled all the ports I had and then tried installing openjdk6, which again gave me the above error. I then completely removed the MacPorts installation (using the command on the macports website for uninstalling (rm -rf ...) and reinstalled it, and then retried the openjdk6 install. Here is the text with -d from the most recent openjdk install attempt:
