I ran into this too. (The dcron vs vixiecron part anyway).
When I unmerged vixie-cron it failed to remove /etc/init.d/vixie-cron.
Run this to remove cron from any runlevels

rc-update delete vixie-cron

Then remove /etc/init.d/vixie-cron

Now run

rc-update add dcron default

The permission denied from crontab is happening because your user is
not in the cron group.

Is the user in the cron group?

since anything under /etc is in CONFIG_PROTECT (except those listed in
CONFIG_PROTECT_MASK of course), portage won't touch it, so when you unmerge
things that have services in /etc/init.d you will need to manually remove the
init script (just rm it).

env-update is just complaining because there's two different init scripts
providing the same service.

Try deleting the dcron directory in /etc/init.d/, and make sure you've
done a "rc-update add vixie-cron default". That should take care of
the confusion between dcron and vixie-cron.

I'm running into the same problem on permissions. I haven't had the
problem in the past. I'm not sure if the devs have tightened security
in some (undocumented) way, or if there is just a problem with the
ebuild. I'm researching, I'll post anything I find.
