在Redhat安装Oracles前需要按照依赖包，但是在安装elfutils-libelf遇到了两个包相互依赖的情况
[root@rhvm1 /]# rpm -i elfutils-libelf-devel-static-0.137-3.el5.i386.rpm
warning: elfutils-libelf-devel-static-0.137-3.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897
error: Failed dependencies:
elfutils-libelf-devel-i386 = 0.137-3.el5 is needed by elfutils-libelf-devel-static-0.137-3.el5.i386
[root@rhvm1 /]# rpm -i elfutils-libelf-devel-0.137-3.el5.i386.rpm
warning: elfutils-libelf-devel-0.137-3.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:
elfutils-libelf-devel-static-i386 = 0.137-3.el5 is needed by elfutils-libelf-devel-0.137-3.el5.i386
如此循环往复下去就一个包也装不上，对于这种相互依赖的情况需要使用在rpm命令之后同时写上两个包来实现。
[root@rhvm1 /]# rpm -ivh elfutils-libelf-devel-0.137-3.el5.i386.rpm elfutils-libelf-devel-static-0.137-3.el5.i386.rpm

如此就安装上了这两个包。
