安装samba时提示的错误信息，帮忙看看

13683507141

[root@npisa 111]# rpm -ivh samba-swat-2.2.5-10.i386.rpm
warning: samba-swat-2.2.5-10.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e
error: Failed dependencies:
        samba = 2.2.5 is needed by samba-swat-2.2.5-10
        xinetd is needed by samba-swat-2.2.5-10
        libcups.so.2 is needed by samba-swat-2.2.5-10

小弟是初学者，不知道为什么装不了。所提示的依赖文件不就是我需要安装的东西吗？
装samba-2.2.5-10.i386.rpm        
   samba-common-2.2.5-10.i386.rpm
   samba-client-2.2.5-10.i386.rpm
都会出现如上提示，究竟是什么情况呢？

安装2.2.5先,后装~-10试了没!
