DragonFlyBSD

Update through (I have been using full buildworlds after latest updates including cleaning /usr/obj/usr):

commit b34d3b9b8fa26892a7eb1f0fbf9a053d72798cd8
Date: Thu Mar 10 10:43:31 2016 +0200

nrelease: Allow to build snapshots on tmpfs.

After installation,

cd /usr/obj
mv usr usr.prev

because it appears one needs a functioning /usr/obj/usr to build anymore.

Now update through:

commit 3eec877432eb8056a5450dd96fad6f6abad016b9
Date: Fri Mar 11 20:11:40 2016 +0100

ncurses: Upgrade version 5.9 (20110402) => 6.0 (20160305)

cd /usr/src
make buildworld

Not long into the build, reproduced on 2 separate machines so far:

The /etc/make.conf used is:

On one machine, moving back /usr/obj/usr allows
make quickworld
to complete successfully. However I have not attempted to install this world yet.
