[Serusers] RE: SERWEB error: "Function aggergate_method() doesn't exists."

I'm currently running Fedora Core 4, SER 0.9.2, and have followed the instruction of running: # pear install -f classkit and when I run: # pear list I receive the following output: Installed packages: =================== Package Version State Archive_Tar 1.1 stable Console_Getopt 1.2 stable DB 1.7.6 stable HTML_Template_IT 1.1 stable HTTP 1.3.5 stable Mail 1.1.4 stable Net_SMTP 1.2.6 stable Net_Socket 1.0.6 stable Net_UserAgent_Detect 2.0.1 stable PEAR 1.3.5 stable XML_Parser 1.2.6 stable XML_RPC 1.2.2 stable classkit 0.4 beta runkit 0.3.0 beta but it's still giving me the "Function aggregate_methods() doesn't exists. Try install Classkit extension. http://pecl.php.net/package/classkit" error. I even installed the runkit which is supposed to be the next version up. Can anyone recommend anything to resolve this error?? I'm more of a perl man, so I'm lost with PHP. Thanks. Gareth
