I just ran into this problem, too.  It turns out that it was due to
LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib being set which is causing
the loader to pick up the wrong library.

Clearing the problem and resuming the build ends up being simple:
	# unset LD_LIBRARY_PATH
	# make -DNO_CLEAN buildworld

(Csh users will need unsetenv).
