安装pecl - 致命错误:找不到'php.h'文件

Question

我正在尝试安装PECL OAuth,但我收到一条错误消息(我使用macbook mountain lion).

 In file included from /private/tmp/pear/temp/oauth/oauth.c:14:
/private/tmp/pear/temp/oauth/php_oauth.h:20:10: fatal error: 'php.h' file not found
#include "php.h"
     ^
1 error generated.
make: *** [oauth.lo] Error 1
ERROR: `make' failed

有人知道怎么解决吗？

谢谢,尼米
