how to fix vcron/vixie-cron issues

gentoo decided to rename the package for vixie cron from vcron to vixie-cron. If you had this happen in the middle of a bunch of upgrades, you missed the info on how to fix it. So I don’t lose this link again:

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