thanks for responding so promptly. ld64 has now been built correctly 
with the new unwind, but it seems that libunwind is troubling other 
ports as well.
The next of my outdated ports to be upgraded was gcc, to go from 4.8.2 
to 4.9.1. This build also fails, and again it seems to be unwind that is 
causing the trouble. Below I have included the error messages pertaining 
to the failure.
