今天在安装mysql时遇到了上面这个问题，解决办法：安装GCC软件套件
 [root@server mysql-5.0.56]# yum install gcc
Loaded plugins: fastestmirror

再次运行上面命令安装mysql即可以正常安装：
[root@server mysql-5.0.56]# ./configure --prefix=/usr/local/mysql --with-charset=gbk --with-extra-charset=all --enable-thread-safe-client --enable-local-infile --with-low-memory
