先要多谢Czz跟ELM两位大虾的指点。:-)
今天终于解决了在freebsd下面innbbsd的安装问题。

症状如下：
在FreeBSD4.2下面编译
Makefile其中一部分如下

# Generated automatically from Makefile.in by configure.
# Makefile of innbbsd for Firebird BBS 3.0
#
# $Id: Makefile.in,v 1.12 2000/07/25 09:14:01 edwardc Exp $
##########################################################

VERSION         = 0.50beta-5F
NCMVERSION      = NoCeM_0.66

ADMINUSER = SYSOP.bbs@bbs.szu.edu.cn
BBSHOME = /home/bbs
BBSHOST = bbs.szu.edu.cn
BBS_SRC = /root/src/bbssrc
PERL    = /usr/bin/perl

LANG = GB
-------------------------------------------------------

#make freebsd && make install

接着设置bbsname.bbs newsfeeds.bbs nodelist.bbs

# su bbs
$ /home/bbs/innd/innbbsd
su-2.04$ /home/bbs/innd/innbbsd
su-2.04$ PID file is in /usr/tmp/innbbsd-7777.pid
Try to listen in port (null) and path (null)
Trying to listen in port 1904
Trying to listen in port .innbbsd1
bind: Address already in use
.innbbsd1: Address already in use
Trying to listen in port .innbbsd2
.innbbsd2/tcp: Unknown service.
local pmain, existing: Address already in use
if no other innbbsd running, try to remove (null)

或者出现跟这个类似的信息

%PID file is in /usr/tmp/innbbsd-7777.pid
Try to listen in port (null) and path (null)
Trying to listen in port 1904
Trying to listen in port .innbbsd1
bind: Permission denied
.innbbsd1: Permission denied
           ~~~~~~~~~~~~~~~~~~就这个不同  
Trying to listen in port .innbbsd2
.innbbsd2/tcp: Unknown service.
local pmain, existing: Permission denied
if no other innbbsd running, try to remove (null)

但是在Redhat 6.2下面编译后运行就没问题。

[bbs@fly innd]$ PID file is in /usr/tmp/innbbsd-7777.pid
Try to listen in port 7777 and path /home/bbs/innd/.innbbsd

[bbs@fly innbbsd]$ telnet localhost 7777
Trying 127.0.0.1...
Connected to fly.szu.edu.cn.
Escape character is '^]'.
200 flyBBS InterNetNews INNBBSD server 0.50beta-5F_NoCeM_0.63

(bbs@fly.szu.edu.cn).

quit
[bbs@fly innd]$

说明是freebsd自己的问题。
再继续追查原因。用暴力法把那个端口也改了，还是不行。
分析下面这段错误信息：
su-2.04$ /home/bbs/innd/innbbsd
su-2.04$ PID file is in /usr/tmp/innbbsd-7777.pid
                                         ~~~~这里表明port还是用默认的7777
Try to listen in port (null) and path (null)
                      ~~~~~~~          ~~~~~~但这两个就变了。
Trying to listen in port 1904

[bbs /root/src/bbssrc/util/innbbsd]# grep "Try to listen in port" *
dbzserver.c:            fprintf(stderr, "Try to listen in port %s and path

%s\n",
port, path);
inndchannel.c:          fprintf(stderr, "Try to listen in port %s and path

%s\n",
port, path);

找到两个地方。我想，既然不知道port跟path在什么时候被改变了，那不如加一个

static看看怎样吧。

就在main函数开始那里有port跟path的定义:
main(argc, argv)
int     argc;
char  **argv;
{

        static char   *port, *path;/* 加一个static的声明 */
        int     c, errflag = 0;
        extern  INNBBSDhalt();
#if !defined(DBZSERVER)
        initial_lang();
#endif  

重新make
运行innbbsd
PID file is in /usr/tmp/innbbsd-7777.pid
Try to listen in port 7777 and path /home/bbs/innd/.innbbsd

噢。。终于行了，
#telnet localhost 7777
Trying 127.0.0.1...
Connected to localhost.szu.edu.cn.
Escape character is '^]'.
502 You are not in my access file. (unknown@localhost.szu.edu.cn)
Connection closed by foreign host.

那两个指针具体在哪里被改变就不清楚了，反正加了static就没事。希望这些能对遇到同
类问题的人有所帮助。:)
