Thanks. I see the directories I needed were added back in May to 
NetBSD.dist.

I didn't think NetBSD.dist was for this since the "make includes" does do 
many "mkdir -p" for many include directories also.

Should "make includes" do the "distrib-dirs" target first?

Or is it not normal to run "make includes"?
