Getting RT to work with mod_perl 2.0 (specifically on Centos 4) (updated wiki)

I just rebuild a box with the latest Centos and put RT on it. I ran into
the usual problems with mod_perl 2.0, and didn’t remember how I solved
it before, so I worked it out again. This time, I was smart enough to
put it on the wiki!

(incidentally, I used to be able to log into the wiki so that changes
were flagged with my name, this time I couldn’t find a way to login.
Does anyone know what’s up with that?)
