# gssapi is just the framework, we really require kerberos v5, so
# look for those headers (the gssapi headers must be there, too)
# The problem with this implementation is that it doesn't allow
# for the specification of gssapi and krb5 headers in different locations,
# which probably ought to be fixed although fixing might raise the issue of
# trying to build with incompatible versions of gssapi and krb5.

		# 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
