安装ORACLE的时候GCC包打不上，换以下错误：

[root@cump oracle]# rpm -ivh gcc-4.1.2-48.el5.x86_64.rpm

warning: gcc-4.1.2-48.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

error: Failed dependencies:

libgomp >= 4.1.2-48.el5 is needed by gcc-4.1.2-48.el5.x86_64

弄了半天，查询才知道，原来这个包是有依赖的包，要先安装libgomp这个包才能安装：

[root@cump oracle]# rpm -ivh libgomp-4.4.0-6.el5.i386.rpm
