qmail1.03安装问题?我安装了很多次都一样。。

[lpczs]

前辈，帮帮小弟。
我用的是Red Hat AS 4.0。我想在上面安装Qmail1.03。我在执行这语句时编译到这里就出错了。

./compile maildirquota.c
maildirquota.c :37:20: string.h 没有那个文件或目录
make: *** [maildirquota.o] 错误1

有什么办法解决？

以下是我参考网上的文章安装的过程：
-------------------------------
安装ucspi-tcp-0.88
#tar zxvf ucspi-tcp-0.88.tar.gz
#cd ucspi-tcp-0.88
#patch -p1 < ../ucspi-tcp-0.88.a_record.patch
#patch -p1 < ../ucspi-tcp-0.88.errno.patch
#patch -p1 < ../ucspi-tcp-0.88.nobase.patch
#make
#make setup check

安装qmail
1.下载软件及补丁：
wget http://cr.yp.to/software/qmail-1.03.tar.gz
wget http://www.ckdhr.com/ckd/qmail-103.patch
wget http://www.qmail.org/qmailqueue-patch
wget http://www.shupp.org/patches/qmail-maildir++.patch
wget http://qmail.te8.com/rpms/glibc-2.3.1/qmail-1.03.errno.patch
wget http://qmail.te8.com/rpms/glibc-2.3.1/qmail-1.03.qmail_local.patch
wget http://members.elysium.pl/brush/qmail-smtp-auth/dist/qmail-smtpd-auth-0.31.tar.gz
2.建立目录：
# mkdir /var/qmail
# mkdir /var/qmail/alias
3.建组及用户：
# groupadd nofiles
# groupadd qmail
# useradd alias -g nofiles -d /var/qmail/alias -s /nonexistent
# useradd qmaild -g nofiles -d /var/qmail -s /nonexistent
# useradd qmaill -g nofiles -d /var/qmail -s /nonexistent
# useradd qmailp -g nofiles -d /var/qmail -s /nonexistent
# useradd qmailq -g qmail -d /var/qmail -s /nonexistent
# useradd qmailr -g qmail -d /var/qmail -s /nonexistent
# useradd qmails -g qmail -d /var/qmail -s /nonexistent
4.打补丁及编绎安装qmail
#tar zxvf qmail-1.03.tar.gz
#tar zxvf qmail-smtpd-auth-0.31.tar.gz
#cp qmail-smtpd-auth-0.31/base64.* qmail-1.03 //安装smtp-auth补丁，支持smtp认证
#patch -d qmail-1.03 < qmail-smtpd-auth-0.31/auth.patch
#cd qmail-1.03
#patch -p1 < ../qmail-103.patch
#patch -p1 < ../qmailqueue-patch
#patch -p1 < ..qmail-maildir++.patch
#patch -p1 < ..qmail-1.03.errno.patch
#patch -p1 < ..qmail-1.03.qmail_local.patch
#vi qmail-smtpd.c //将函数straynewline中的451改为553
# make setup check //*就是这地方出问题了。

我现在参考这网页（http://blog.chinaunix.net/u/24390/showart_250269.html），这一步通过了。但是又遇到问题了，那就是vpopmail在编译时出错了。

编译代码：

我下载了5.4.18,5.4.12,5.4.1这几个版本都是这样的。
在网找了一下有关这问题的文章都很多，但是没有一个有解决方法的？谁能帮帮我？

我用的系统是Red Hat As 4.0,内核是2.6的。Redflag ws 5又是一样的问题。
