make ZEND_EXTRA_LIBS='-liconv'
make install

出现错误：

Fatal error: Error: cannot open phar
"/root/soft/php-5.2.10/pear/install-pear-nozlib.phar" in
/path/php-5.2.10/pear/install-pear-nozlib.phar on line 795
make<1>: ***  Error 255
make: ***  Error 2

解决方法：

编译参数里面加入：
--without-pear

安装好php以后，如果需要装pear，直接安装二进制的pear。
例如，按下面的方法：
curl http://pear.php.net/go-pear | /usr/local/php/bin/php
