Yes, I'm running inside the src tree (I thought that was clear from my 
posted command sequences).

But this answer (and the other answer to run "make obj" before) put me 
on the right track.

Moving mk.conf out of the way didn't help either. Error message now 
indicated a missing directory in the /usr/obj tree.

I have

[muc-twinppc:/local/netbsd-src/src/sys/arch/macppc/compile/GENERIC]$ ls 
-l /usr/obj
lrwxr-xr-x  1 root  wheel  21 Jul 17  2013 /usr/obj@ -> 
/local/netbsd-src/obj
[muc-twinppc:/local/netbsd-src/src/sys/arch/macppc/compile/GENERIC]$

After moving /usr/obj away, it works now:

The subsequent "make" run successfully built a kernel.

Thanks all for your help.

Is there some default, that if /usr/obj exists, it's automatically used?
