ipvsadm 编译问题。

看过之前大家遇到的问题，也阅读了wiki上面的步骤。依然没法解决。
redhat version: Red Hat Enterprise Linux ES release 3 (Taroon Update 2)
kernal version: 2.4.21-15.ELsmp
[root@dhcppc15 ipvsadm-1.21-11]# modprobe ip_vs
[root@dhcppc15 ipvsadm-1.21-11]# cat /proc/net/ip_vs
IP Virtual Server version 1.0.8 (size=65536)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn

错误信息为：
[root@dhcppc15 root]# cd ipvsadm-1.21-11
[root@dhcppc15 ipvsadm-1.21-11]# make

software页面上tar文件
ipvsadm-1.21-11.tar.gz - January 22, 2005 //编译不通过。
ipvsadm-1.21.tar.gz - October 27, 2004 //编译通过。

请教大家:)
