sendmail??????????

sendmail??????????

我在配置sendmail的时候为了生成/etc/sendmail.cf,执行如下命令:
m4 ../m4/cf.m4 redhat.mc > /etc/sendmail.cf
出现如下错误:
redhat.mc:32:m4:Cannot open ../feature/.m4 No such file or directory.
请问该如何解决。

      
有什么东西没有装全吧!      
大哥,这我也能猜到,但该怎么做呢?
怎样装个m4?      
full install.remember must full install.      
thanks, I will try again later.
