It's surrounded by 

.if !defined(X11BASE)
X11BASE=        /usr/X11R6
.endif

Which would protect it if it was defined;
but I don't see where X11BASE is defined anywhere in 
  /usr/ports/Mk
  /usr/share/mk

If it's been obsoleted, that would be the problem.

However, I don't see LOCALBASE defined anywhere except in terms of itself, either.
Where is it initially set?
Not being a make dude, I'm out of my element here
