怎么来安装yum

怎么来安装yum

各位高高手好:
               我有 [yum-2.4.3-1.C4.noarch.rpm]  我该怎么来安装它呢??
先用rpm -ivh 包名
然后就要配置了。具体看下面的
Fedora Core9的YUM配置:http://www.linuxdiyf.com/bbs/thread-92032-1-1.html

我现在一用这语句就出现这样的东东
#rpm -ivh yum-2.4.3.1.rpm
warning:yum-2.4.3.1.rpm: v3 dsa signature:nokey,key id 443e1821
error:failed dependencies:
       python-elementtree is needed by yum-2.4.3.1
       puthon-sqlite is needed by yum-2.4.3.1
       urlgrabber is needed by yum-2.4.3.1
       yumconf is needed by yum-2.4.3.1
根本连解压都解不了啊
