Error Installing PEAR

[ThePsion5]

Ok, so I'm trying to install PEAR. I unzip the files to my PHP directory and run the go-pear.bat file. The include path is set to ".;C:\php\includes;C:\php\PEAR" my extension directory is set to "C:/php/ext/" and i've run the go-pear.bat file and gone through it. Added the pear directory to the PATH variable, restarted the computer. Unfortunately, when i try to require it in one of my files, i recieve the following error:

Fatal error: Require: Failed opening required 'DB.php'(include_path='.;C:\php\includes;C:\php\PEAR') in (document path & line #)

To the best of my knowledge i've configured everything correctly...what's going on?EDIT: By the way, I'm running Windows XP with Apache 2.0.55 and PHP 5.1.2 and MySQL 5.0.18-nt.
