It was redmine I was using when I had the issues actually. The real problem though was that I was trying to use a newer version of Redmine than was available in the repo, and I did still manage to satisfy the dependencies but upgrading my Ruby version broke literally everything.

I think if 100% of your eco system is from the package manager you would be fine, but if even a single component needs to come from outside I would reach straight for rvm and bundler (no prejudice against rbenv, rvm is just what I use)
