Yeah, sadly Ruby has the same environment issues as Python. Python has virtualenv, Ruby has rbenv - they're essentially required, sometimes even for global binaries. For Python, there's `pipsi` for automatically creating unique virtualenvs for binaries - that's the right approach, and it's worth adopting ASAP for future sanity. It even lets you mix python 2 and 3 binaries without any issues. I don't know what the equivalent would be for Ruby.
