	when compiled for dbm (-DNDBM in sendmail compilation), sendmail 8.11.0
	tries to use dbm_pagfno().  NetBSD does not supply the function
	(/usr/include/ndbm.h disables it by a #define)

	db (-DNEWDB, IIRC) seem to work fine.

	see src/gnu/usr.sbin/sendmail/Makefile.inc for declarations that are
	currently enabled.

	not 100% sure how things are defined in NetBSD sendmail build
	in the past.  src/usr.sbin/sendmail/src/Makefile has the following
	declarations, just like the current declaration: -DNEWDB -DNIS
