atomicturtle, I found the yum.conf entries I needed to use your service (thank you very much by the way!) but I have sitebuilder installed which requires php-xslt, and this fails for 4.3.10.
I've actually been running linux since 1992, and I have a RH 7.3 box I've kept up-to-date with source code which is running PHP 5.0.3 no problem, but I'm completely new to yum and my experience with RPM's have been pretty well limited to the installer. I'd be willing to generate this package myself, but to be honest I don't have much of a clue even where to start. I'll start digging anyway and see where I end up.
This box has been an experiment for me to see if it is time for me to give up on my old fasioned ways of downloading source tarballs and give myself a free ride on yum/rpm/plesk. Somehow I don't think its going to be as easy as I'd hoped. Still, if I can learn how to be a contributer and reduce my work load I'd still come out ahead.
Thanks again for providing the atomicturtle yum repository, and what I'm sure add up to countless hours maintaining it.
