运行/usr/local/webserver/php/bin/phpize时出现：
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
第一种方法是：
# cd /usr/src
# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz
# tar -zvxf m4-1.4.9.tar.gz
# cd m4-1.4.9/
# ./configure && make && make install
# cd ../
# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz
# tar -zvxf autoconf-2.62.tar.gz
# cd autoconf-2.62/
# ./configure && make && make install
本人使用第二种更简单的办法:
# yum install m4
# yum install autoconf
