MySQL and PHP - What are you using?

["Lehman, Jason (Registrar's Office)" <Jlehman admin usf edu>]

I am trying to figure out if most people are sticking to what is
distributed with the Enterprise CDs or are they getting the latest
versions and installing them?  If you are, are you rolling your own rpms
or are you getting the rpms from somewhere else, "Where?", or are you
compiling?  Thanks for the help in advance.
