First, regarding the buildworld failure: yup, you probably missed some 
sources. Or, you forgot to set up /etc/make.conf properly. If you've 
never touched make.conf, buildworld assumes you have all sources. Since 
you downloaded only some of them, buildworld will eventually try to 
build something for which you do not have the sources. Using 
/etc/defaults/make.conf as a reference, setup make.conf to only build 
the stuff you think you need.

Second, regarding the status of your upgrade: my guess is that you're 
running a 4.10 kernel, and a partially 4.10 world. Check it out by 
running programs that interact closely with the kernel. ps(1) and top(1) 
are such programs. If they act "weird", you probably still haven't quite 
managed to upgrade.
