You type:	emerge <whatever>
You get:

Problem:	There is a naming conflict with the packages, I think vcron was
		officially renamed to vixie-cron because Mr. Vixie's ego was
		hurting and/or he wanted to just make us type more. Anyhow...
	
		There are a bunch of posts on gentoo forums about this, this
		one has links to the others:
		http://forums.gentoo.org/viewtopic.php?t=121455

Solution:	Basically we need to get rid of vcron. As root:

		/etc/init.d/vcron stop
		emerge unmerge vcron
		rc-update del vcron
		rm /etc/init.d/vcron
		rc-update add vixie-cron default
		/etc/init.d/vixie-cron start

Verify:		You shouldn't get the message anymore :P
