原问题：

我在 CentOs 5 机器上安装 PHP Pecl Intl 扩展时遇到问题。

安装后icu并libicu使用以下命令：

$ yum install icu
$ yum install libicu

我尝试像这样安装 Intl 扩展：

$ /usr/bin/pecl install intl

我选择搜索 ICU 库和头文件的默认位置。它最终会像这样崩溃：

checking whether to enable internationalization support... yes, shared
checking for icu-config... no
checking for location of ICU headers and libraries... not found
configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works.
ERROR: `/tmp/pear/temp/intl/configure --with-icu-dir=DEFAULT' failed
