yum源里找不到 php54w-devel,求可用yum源

rpm -Uvh http://repo.webtatic.com/yum/...

我的是php5.4，centos6.7,可是更新了yum源依然找不到 php54w-devel,哪里有可用的yum源？
还是说下载了yum源之后需要先 yum install php54w,然后才能执行 php54w-devel?

webtatic已经不支持php5.4的扩展包了。。。。
在我另一台服务器上 yum list | grep php54,发现有php54w-devel

我要怎么找到这个 php54w-devel的rpm包在哪里？
用find / -name php54w-devel* 找不到

如果时间允许，建议还是学学如何通过源码编译php。
