		# Essentially the problems here relate to two different

		# or MIT Kerberos, particularly when both are present on
		# the machine.  The other is static versus dynamic linking.
		#
		# On the KTH vs MIT issue, Both have libkrb5 that can mess
		# 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
		# problems start to show up.
