ruby

Dear all,

How are you? I hope all is well with you. Sometime ago I was recommended to use rbenv script (https://github.com/rbenv/rbenv) to manage multiple installations and versions of Ruby. I followed that advice and have no problems since then. You just need to set it up properly. Read the installation guide on the GitHub page. I hope it helps you. Thank you and have a wonderful day ahead!

Best wishes,

>> Yeah, this is the answer. You always want `/opt/local/bin/` to be near the start of your path. Only stuff that you specifically want to override MacPorts should be before it. (Examples of things you may want before: RVM or NVM or any of the version managers that put things in your home)
