recent update seems to break portupgrade

I just tried to do a portupgrade and received the following on the command 
line.  I compiled my system (world and ports from source).  Portupgrade 
worked earlier today before I upgraded to r240078.

# portupgrade -va

Not sure what is going on, I guess it is related to pkg:

# whereis pkg
pkg: /usr/sbin/pkg /usr/local/man/man8/pkg.8.gz /usr/src/usr.sbin/pkg
[root_at_FBSD10 ~]# ls -l /usr/sbin/pkg
-r-xr-xr-x  1 root  wheel  16256 Sep  3 13:55 /usr/sbin/pkg

If I do not want to use pkg do I need an entry in /etc/src.conf?  How do 
you disable pkg?  How do I run portupgrade now?
