Make installworld fails on file not found (Error code 71)

from Jeffrey Bouquet:

Sure, I used single user mode, as advised in UPDATING file.

from Sergey Kandauro:

I ran "make buildworld" successfully, and "make kernel" before rebooting into single-user mode, mergemaster -Fp and make installworld.
