This is my second time trying to install Ruby on my system. This time I've following http://railsapps.github.io/installrubyonrails-mac.html. I've followed the steps and keep getting hung up with the error below. At this point, I've backtracked and removed RVM and Homebrew, but now I'm seeing this error. I've searched stack overflow, google, etc. There are similar issues but they're all not related to system files. Any ideas where I can start?
