我安装时用的是默认安装，所以说GCC也没有装进去。
GCC在安装源码包时要用到的一个组件，
开始安装：按顺序安装以下包就可以完成GCC的安装了
1) [root@rhel5 Server]# rpm -ivh kernel-headers-2.6.18-53.el5.i386.rpm
2) [root@rhel5 Server]# rpm -ivh glibc-headers-2.5-18.i386.rpm
3) [root@rhel5 Server]# rpm -ivh glibc-devel-2.5-18.i386.rpm
4) [root@rhel5 Server]# rpm -ivh libgomp-4.1.2-14.el5.i386.rpm
5) [root@rhel5 Server]# rpm -ivh gcc-4.1.2-14.el5.i386.rpm
6) [root@rhel5 Server]# rpm -ivh libstdc++-devel-4.1.2-14.el5.i386.rpm
7) [root@rhel5 Server]# rpm -ivh gcc-c++-4.1.2-14.el5.i386.rpm
下面的是我安装时的日志：
[root@rhel5 Server]# rpm -ivh gcc-4.1.2-14.el5.i386.rpm

PS：呼。。。。终于装上了。

OK大功告成。
总结：安装时注意看提示，看提示需要先安装那一个包。要学会分析，一步一步的装就可以搞定了。如：
[root@rhel5 Server]# rpm -ivh gcc-4.1.2-14.el5.i386.rpm
warning: gcc-4.1.2-14.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:
glibc-devel >= 2.2.90-12 is needed by gcc-4.1.2-14.el5.i386
//意思是gcc-4.1.2-14.el5.i386依赖于glibc-devel，必要先安装glibc-devel
libgomp = 4.1.2-14.el5 is needed by gcc-4.1.2-14.el5.i386
//意思是gcc-4.1.2-14.el5.i386依赖于glibc-devel，必要先安装libgomp
libgomp.so.1 is needed by gcc-4.1.2-14.el5.i386
这里面就有两个依赖包，只有把它安装好了之后才能安装GCC。
