PEAR Installer Error

Hello, First of all I'd like to thank all you marvelous PHP/PEAR developers and maintainers. If it wasn't for you, I'd still have a PERL induced headache. I used the web installer (go-pear.php) on WinXP, Apache 1.3.27, PHP 4.3.2 RC2. After doing the same on a Win2K a while back, I was very pleased to see that all of the installation problems were fixed (everything went where it was supposed to). However, the package manager does not work. I get the following error at the top of the page "XML_RPC_Value: scalar can have only one value" with the following message as the intended PEAR_Error output "The package list could not be fetched from the remote server. Please try again. (Debug info: "0")" Has anyone else had this trouble? How do I fix it? I have searched this mailing list without any luck. I know that the package manager is not a necesity, but it is a nifty tool and I'd like to get it working if I can. Thanks, Dan
