# $NetBSD: netbsd-proto.mc,v 1.10 2002/09/30 01:27:05 grant Exp $
を見つけて来て ./Build すると、

ttyp0:makoto@harry 7:48:21/030319(...cf/cf)> ./Build netbsd-proto.cf

となってしまうので、

して、

ttyp0:makoto@harry 7:52:44/030319(...cf/cf)> ./Build netbsd-proto.cf
Using M4=/usr/pkg/bin/gm4
rm -f netbsd-proto.cf
/usr/pkg/bin/gm4 ../m4/cf.m4 netbsd-proto.mc > netbsd-proto.cf || ( rm -f netbsd-proto.cf && exit 1 )
*** WARNING: missing -T<TMPF> in argument of FEATURE(`access_db', hash -o /etc/mail/access)
chmod 444 netbsd-proto.cf

のように書くらしい。WARNING だからいいとは思うが、 一応試す。

名前をまじめに設定する必要がありそう。
