我正在按照这里的说明安装 mcrypt：http://michaelgracie.com/2012/09/26/plugging-mcrypt-into-php-on-mac-os-x-mountain-lion-10-8/
一切似乎都运行正常，直到我进入运行 /usr/bin/phpize 后的步骤并尝试使用 libmcrypt 配置 php。这是我在终端中运行的内容和输出：

我下载了 libmcrypt-2.5.8 和 php-5.3.6，所以我不确定为什么它会将版本读为 2.5.6。也许还有另一个较旧的 libmcrypt 文件在流传？如果是这样，我该如何找到并删除它并继续？我使用的是 Mac OS X 10.7.5。
