[freddo]

Hi,
When trying to install "Fileinfo" in WHM via
Main >> Software >> Module Installers PHP Pecl Installer

I get the following error:

WARNING: "pear/Fileinfo" is deprecated in favor of "channel://php-src/ext/fileinfo/in php sources"
downloading Fileinfo-1.0.4.tgz ...
Starting to download Fileinfo-1.0.4.tgz (5,835 bytes)
.....done: 5,835 bytes
3 source files, building
running: phpize
Cannot find config.m4.
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module

ERROR: `phpize' failed
The Fileinfo.so object is not in /usr/local/lib/php/extensions/no-debug-non-zts-20060613

any help would be highly appreciated
Thanks
Fred
