"make" in ports tells me "requires kernel source files in SRC_BASE=/usr/src." despite an up-to-date /usr/src

FWIW, I am not seeing the issue.  Having said that, the trailing dot 
after /usr/src in that error message looks suspicious, it is not there 
in /usr/ports/Mk/Uses/kmod.mk; was that an exact copy/paste?  If yes, 
check if you are (incorrectly) setting SRC_BASE somewhere?
