I've been trying to get Conductor running with rvm and Bundler, versus using system ruby. (I've been semi-inaccurately referring to this as "upstream" ruby, based on our desire to work upstream in pure ruby, without requiring Fedora.)
I opened https://www.aeolusproject.org/redmine/issues/3447 to track getting cucumber tests to pass there.
I ran these against ruby 1.8.7 patchlevel 357, using Bundler which got me 3.2-series Rails. With both of these in place, and various services running, I have only failure left (see task #3450 -- it seems to be reaching live Image Factory, and I'm not going to be able to fix this today, so I'm sending this out now.)
Note that, ideally, this should be tested two ways -- one on "upstream" ruby with Bundler, and the other against system ruby to make sure I didn't break anything.
We do want to get tests working with Ruby 1.9, and with all external services disabled, but that's not my focus with these particular patches.
