Ruby users faced it with Gem and solved it with dependency freezing.
Ruby didn't solve it for anyone but developers. End users are required to build what amounts to a separate Ruby installation using RVM for every Ruby application, because every application works with only its curated sets of gems.
This is, quite simply, nonsense. You've pushed the whole problem into the user's lap and required them to do a lot of extra work for every application they want to use. This "solution" is exactly the thing I want to *avoid*.
