Am I missing something here?  The Makefile for libexec/talkd is as follows:

#	from: @(#)Makefile	5.10 (Berkeley) 5/11/90
#	$Id: Makefile,v 1.3 1994/12/22 10:28:15 cgd Exp $

PROG=	ntalkd
SRCS=	talkd.c announce.c process.c table.c print.c
MAN=	talkd.8

.include <bsd.prog.mk>

This creates ntalkd.  How does talkd get created?
