Apologies for the delay in getting back on this.

The usecase here is where someone checks out individual ports as
opposed to the entire tree or subtrees and builds them.

This works very fine in general, there are but one or two ports
where this fails for me.  graphics/libGLU is one of them.


I am pretty convinced my patch is not less correcty technically,
but rather more.  It works both with a full ports checkout, and
the scenario I describe below.

Do you approve?
