在卸载RPM包时，报错specifies multiple packages；通过查询看到同一个包安装了两次，所以报错了，需要指定包。
[root@fanyk ~]# rpm -qa |grep curl
curl-7.15.5-17.el5_9
curl-devel-7.15.5-17.el5_9
TWWcurl715-7.15.1-2
curl-devel-7.15.5-17.el5_9
curl-7.15.5-17.el5_9
TWWcurl715-doc-7.15.1-2
TWWcurl715-man-7.15.1-2
[root@fanyk ~]# rpm -e curl-7.15.5-17.el5_9
error: "curl-7.15.5-17.el5_9" specifies multiple packages

在卸载时，加上参数allmatches即可，这代表卸载所有匹配的包。
[root@fanyk ~]# rpm -e curl-7.15.5-17.el5_9 --allmatches

卸载时还是报错，因为依赖关系，再加参数nodeps ，强制卸载。
[root@fanyk ~]# rpm -e curl-7.15.5-17.el5_9 --allmatches --nodeps
