 	% portupgrade
 	portupgrade: Command not found
 
 If portupgrade is such an obvious solution, then why isn't it used
 automatically?  I have no idea what the side effects will be, I'm not
 going to take a risk on a stable system.
 
 In other words: Why isn't the right version of expat installed when it's
 needed?  Version conflicts should be dealt with, not result in an error
 message.
