Somewhat predictably, removing iTunes on Mac OS X is a long arduous process, described at http://support.apple.com/kb/ht1224 — which I have followed. As far as I can tell, I have purged every trace of the accursed iTunes from my system. Yet Software Update repeatedly prompts me with updates for iTunes, which I don't want anything to do with, despite my saying "Not now" each time. How can I convince Software Update to leave me alone, and never bother me with mention of iTunes again?
I'm on Mac OS X 10.6.4 Build 10F569, and the update being offerred is iTunes 9.2.1.
(Note: Not a duplicate of OS X: why Software Update suggests to update removed application?, whose accepted answer is simply to follow the instructions I mentioned above.)
