Okay, this is wierd. I was continuing to configure this machine on the assumption that the problem would sort itself out... and lo and behold, it did with no apparent reason. I do not recall which of my many aptitude installs did it, but at some point it just stopped showing up as a package to reconfigure... go figure.
sorry I can't be of more help, but maybe the aptitude logs would help? If you'd like them, please let me know. A
