我的开发环境是Mac 10.11.1，XAMPP for OS X 5.6.12。 我想为XAMMP安装memcached，请参考http://wiki.cerbweb.com/Setup:Development/XAMPP/Mac_OS_X#zlib：
Memcache
- sudo /Applications/XAMPP/xamppfiles/bin/pecl install memcache
- 'Yes' when prompted
- stop and start Apache from XAMPP Control Panel.app
- Confirm memcache extension in http://localhost/xampp/phpinfo.php
但是当我运行sudo /Applications/XAMPP/xamppfiles/bin/pecl install memcache时
它是这样的：
gaosongdeMacBook-Pro:bin gaosong$ sudo /Applications/XAMPP/xamppfiles/bin/pecl install memcache

但是我已经通过自制软件安装了ZLIB：
gaosongdeMacBook-Pro:~ gaosong$ brew install zlib
Warning: homebrew/dupes/zlib-1.2.8 already installed
我使用--with-zlib-dir =指定ZLIB包含的前缀和库的位置：
sudo ./pecl install memcached --with-zlib-dir=/usr/local/opt/zlib
或
sudo ./pecl install memcache --with-zlib-dir=/usr/local
但结果相同：（
你能帮我成功安装内存缓存吗？ 非常感谢你！
