I agree, it's going to be a problem eventual. But at least
for the time being most distros are reverting the removal of
the NIS/RPC headers and functions. Beside being a hassle,
libtirpc is not quite ready to be a full replacement -- libtirpc
itself requires some of the NIS headers that glibc-2.14
removes.

It looks like:
	pmap_*
	xdr_*
	clnt_*
	bindresvport
	authunix_create_default
which occur in mount and inetd.

The linking portion of the build log follows:
