centos 6.0 安装lnmp 在安装libcom_err-devel-1.41.12-3.el6.i686.rpm报错，

[root@localhost page]# rpm -ivh libcom_err-devel-1.41.12-3.el6.i686.rpm
error: Failed dependencies:
        /usr/bin/pkg-config is needed by libcom_err-devel-1.41.12-3.el6.i686
        pkgconfig is needed by libcom_err-devel-1.41.12-3.el6.i686

求指导
[解决办法]
先去装一下pkgconfig
