MacOS X Build Fails

Someone suggested the reason my MacOS X build was failing was that I didn't
follow the instructions... That's not the case... I am getting an error
during the 'make' process...

Once again, here is the error:

ar cr libpq.a `lorder fe-auth.o fe-connect.o fe-exec.o fe-misc.o fe-print.o
fe-lobj.o pqexpbuffer.o dllist.o pqsignal.o | tsort`
tsort: cycle in data
tsort: fe-connect.o
tsort: fe-exec.o
tsort: cycle in data
tsort: fe-auth.o
tsort: fe-connect.o
