Ruby on Rails

Phillip,
this problem has already been solved: use RVM. Create a file called ".rvmrc" and put it into the root directory of your project, like this:

rvm use 1.9.2-p290

Whenever you switch into that project (in your terminal) RVM will automatically switch ruby versions.

To get your server to recognize a different ruby version is a little different.

Yea, I think with Passenger/Apache you can configure the PassengerRuby setting on your site to use the Ruby binary you specify. I don't think there's a way to configure it in the app itself. think about it, how would Ruby itself read the config file before determining which ruby binary to use? It's impossible--- catch 22, it has to be in the server's configuration
