Passenger configuration selects which ruby executable to use via a  
global configuration variable (at least for Apache, I assume it’s the  
same for Nginx).

I’m in a situation where I’ve got at least one rails app I’d like to  
run on 1.9 while others remain on 1.8. This is for my development  
machine running OS X 10.6. Normally I just use the Passenger PrefPane,  
which makes a very comfy setup.

With the current state of Passenger, I think doing this would involve  
generating a separate 1.9 version of the Passenger Apache module and  
some how installing both, a probably forgoing the PrefPane for at  
least one of the ruby versions.

Has anyone trod this road before? Is there an easier way. Am I crazy?

Those questions are not meant to be mutually exclusive.

Do you really need Passenger for the 1.9 app? (OK, I’m slighy biased  
here; I think Passenger is kind of silly for development.)

That’s what I would try if I were in this situation.
