我如何安装php-mbstring缺少依赖php-common已经安装

如何让php-mbstring识别php-common?

我正在尝试安装php模块php-mbstring，所以我可以安装phpMyAdmin在php版本5.2.10。

关于我的机器的一些信息:
cpu: Intel(R) Xeon(R) cpu X5355 @ 2.66GHz，宽度:64位
操作系统:centOS

在尝试使用yum安装时，由于依赖项而安装失败。所需的依赖项是否已经安装。也许是版本冲突?最后的。386重要吗?也为什么在我的日志底部描述一个缺失的dll的错误，它不应该寻找一个。so(不确定"它"是在这里)?

已经尝试:

——skip-broken

——nodeps

在.repo文件中修改yum镜像站点

使用下载的rpm安装(我得到相同的错误:需要依赖)下面是我的shell会话，包括yum安装过程和apache错误日志:

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
