[CentOS] Passenger Best Practice

I want to move from running puppet under it's own web brick server, to using passenger.

I'd like to get an idea of how folk are running passenger? Ideally I'd like to keep everything rpm based, so would need ruby enterprise rpms, and then the mod_rails / passenger plugin?

How are you folk doing it?

I've seen:

http://download.elff.bravenet.com/5/x86_64/repoview/mod_passenger.html

And I've also seen:

https://packages.endpoint.com/

Which seems to do some enterprise ruby.

What else is out there? I'm more than happy to do it all myself, but if so it ought to be done in the way which best serves the project...

So... what thoughts / recommendations?
