pear in winxp

I'm having problems getting pear on winxp... I've installed php using the zip package, and running phpinfo it all seems fine... i've enabled some pear packages (DB, other...) but my main goal is to have DB_DataObject running... Thing is i'm trying to run pear-installer with no luck. I've checked some recent messages in here about running go-pear but i can't understand how the whole thing works!! Am i supposed to use go-pear everytime i need a new package? Or is it supposed to be run once on systems where php does not have pear yet? And how do i specify this package i want? The pear.bat script does not work at all... I've put the pear directory in the include_path, but when running the script the pear.in file asks for a getOptions() method that does not exist. Also i've tried using pearwin.php instead of pear.in (no harm trying) but no luck... The command line arguments just don't go anywhere. Now is there some manual way to have the packages running? Where can i get the packages to put them in the pear directory mannualy and add the extension to php.ini? Will this work? Or do i need something else? Excuse me for my ignorance, but i really don't understand the whole process of getting pear packages running... Thank you in advance, Ricardo Rocha
