Odd error at end of "make installworld"

[Kevin Oberman]

I think there is a small issue with the Makefile, although I don't see
exactly what. But I'm no great shakes on Makefiles.

At the very end of the installworld, after completely the makewhatis and
/etc stuff, I got the message that I should not be doing a make world:
WARNING: make world will overwrite your existing FreeBSD
installation without also building and installing a new
kernel.  This can be dangerous.  Please read the handbook,
'Rebuilding world', for how to upgrade your system.
Define DESTDIR to where you want to install FreeBSD,
including /, to override this warning and proceed as usual.
You may get the historical 'make world' behavior by defining
HISTORICAL_MAKE_WORLD.  You should understand the implications
before doing this.

Bailing out now...

But I had not done a 'make world'. I did the standard sequence with a
re-boot after installkernal, a mergemaster -p, and installworld. Since
this message is the second invocation of "world:" in Makefile, I suspect
it needs to be worked on a bit.

FWIW, I was updating from 5.3-Stable of last Wednesday to -Stable of
last evening (to get Nate's ACPI patches).
