I've not used Berkshelf, but I suspect your problems were related to Chef and the fact that they've built their own dependency system that also interacts with Bundler/RubyGems.

Anecdotally, my company has used Ruby since around 2004, and Bundler since its first release, and we never had any issues. That doesn't mean nobody has ever had any issues (clearly! [2]), but it generally seems like Ruby package management is a solved problem, and that it would be a good model for any dependency system to use.

Bundler does have one feature (or misfeature) that Russ Cox criticizes: "bundle install some_gem" can cause unrelated gems' minor (or maybe it's minor) versions to be upgraded even if you don't tell it to. I've never liked that, and would much prefer to use "bundler update" to perform explicit upgrades. But I don't think that behaviour is at all tied to its solver, or that MVS is needed to fix it.
