freebsd下php53extension安装出错

FreeBSD安装php53扩展，遇到如下错误然后中断：

/usr/ports/security/php5-filter/work/php-5.3.15/ext/filter/logical_filters.c:413: error: 'pcre_extra' undeclared (first use in this function)
/usr/ports/security/php5-filter/work/php-5.3.15/ext/filter/logical_filters.c: In function 'php_filter_validate_email':
/usr/ports/security/php5-filter/work/php-5.3.15/ext/filter/logical_filters.c:500: error: 'pcre' undeclared (first use in this function)
/usr/ports/security/php5-filter/work/php-5.3.15/ext/filter/logical_filters.c:500: error: 're' undeclared (first use in this function)
/usr/ports/security/php5-filter/work/php-5.3.15/ext/filter/logical_filters.c:501: error: 'pcre_extra' undeclared (first use in this function)
*** Error code 1
1 error
*** Error code 1

Stop in /usr/ports/security/php5-filter.
 

google后找到解决的方案：

cd /usr/ports/lang/php53/
make extract
cp /usr/ports/lang/php53/work/php-5.3.15/ext/pcre/pcrelib/pcre.h /usr/local/include/php/ext/pcre/

继续安装！

真的佩服那些老外！
