Error: Missing Dependency: cyrus-sasl-lib = 2.1.22-5.el5_4.3 is needed by package cyrus-sasl-md5-2.1.22-5.el5_4.3.i386 (base)
You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package

好像是依赖cyrus-sasl-md5-2.1.22-5.el5_4.3.i386 这个包，于是单独下载了这个包
rpm时却又提示失败的依赖。。。。

没辙了！请大伙赐教，到底错在哪里了~~
