passenger 3 standalone rvm rails

Question

I have a rails app I am trying to run under passenger 3 standalone:

passenger start -a 127.0.0.1 -p 3001 -d

Ive installed this with rvm

cd myapp

rvm use 1.9.2

gem install passenger --pre

I want to set environment variables for my app but can't figure out how and where to set them. I just need to source my .profile which has all my environment variables. How do I do it?

passenger 3: ruby 1.9.2 rails 3 rvm head
