在mac OS lion上的MAMP中尝试使用PECL安装OAUTH时遇到问题

我是设置php服务器的新手，我已经浏览了其他相关帖子，似乎没有人有与我相同的错误。我正在使用MAMP 2.0.2，并运行PHP 5.3.6，并且我正在尝试使用以下命令在本地MAMP上安装oAuth：

$ cd /Applications/MAMP/bin/php/php5.3.6/bin
$ ./pecl install oauth

但是，它会返回这样的错误：

Notice: unserialize(): Error at offset 276 of 1133 bytes in Config.php on line 1050
ERROR: The default config file is not a valid config file or is corrupted.

发生了什么事情？PECL捆绑在MAMP中，它应该开箱即用。

更新：

我在其他地方读到一篇文章，建议配置文件的数据（保存安装路径）不正确，因此我在以下文件中更改了一些值：

/Applications/MAMP/bin/php/php5.3.6/conf/pear.conf

然后，我使用命令：

$ ./pecl install oauth

它开始下载和解压缩，但是当它尝试安装时，它会给出：
