Cannot find autoconf. Please che

运行/usr/local/webserver/php/bin/phpize时出现：

Configuring for:

PHP Api Version: 20041225Zend 

Module Api No: 20060613Zend 

Extension Api No: 220060519

Cannot find autoconf. Please check your autoconf installation and the$PHP_AUTOCONF environment variable. Then, rerun this script.

根据网上的解决办法是：

# 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

###更简单的办法###

# yum install m4

# yum install autoconf
