Oops! I missed a 'not' in there. I meant to type:
.depend still shows that the files in /usr/obj/usr/src/tmp are NOT used.

It ran. It was clearly logged. And /usr/obj/usr/src/tmp/ was populated

ARGH! It was ccache that did me in! Even though I expressly typed "make
-DNOCCACHE", ccache was sneaking in somewhere. I commented out all of
the ccache section of make.conf and it fixed the problem.

Sorry for the wasted bandwidth. If I get a little time, I may try to
figure out why ccache did this, but it's not a high priority.

Thanks very much for your time!
