Make sure that you run '/usr/local/bin/phpize' in the top level source directory of the module

This extension is enabled by default as of PHP 5.3.0. Before this time, fileinfo was a PECL extension but is no longer maintained there. However, versions prior to 5.3+ may use the » discontinued PECL extension.

Php Serial Number

Reference:

This error is displayed because you don't have php-devel package installed

Are you install php-devel?
phpize execute need's php-devel package. if you are on centos run the following code

For me this is working
