		# up the works if one implementation ends up trying to
		# use the other's krb.  This is unfortunately a situation
		# that very easily arises.

		# Dynamic linking when the dependency information is built
		# into MIT's libgssapi_krb5 or KTH's libgssapi magically makes
		# all such problems go away, but when that setup is not
		# present, because either the dynamic libraries lack
		# dependencies or static linking is being done, then the
