Help me to install xmlrpc-epi

Hello,

i want to install xmlrpc-epi. I looking for the sources to compile with 
my php. I am completely loose ... I use php 5.0.3 and apache 2.0.59.
This is my compilation with php:

./configure --prefix=/usr/local/php-5.0.3b \            
--with-apxs2=/usr/app/apache-2.0.59/bin/apxs \             
--with-bz2=/usr/local/bin/bzip2 \        
--enable-soap \            
--with-curl=/usr/local/bin/curl \           
--with-gd=/usr/local \           
--with-zlib=/usr/local/zlib122 \      
--with-zlib-dir=/usr/local/zlib122 \       
--with-libxml-dir=/usr/local \            
--with-xsl=/usr/local \ 
--with-xmlrpc=/usr/local/lib/php

Thanks for your help, that's very important for me ...
