iTunes requires QuickTime 7.5.5 or later...
I just udated a 10.4.11 install to 10.5.8
now when I attempt to open iTunes 10.6.1, I get this error: "itunes iTunes requires QuickTime 7.5.5 or later"
Software update says everything is up to date
I ran Cocktail, Repair Permissions, Repair Disk, rebooted (nothing unusual going on)
I go to http://www.apple.com/quicktime/ and -- NEVERMIND -- I just found the solution here:

QuickTime 7.6.4 includes changes that increase reliability, improve compatibility and enhance security. This release is recommended for all QuickTime 7 users.
