Its quite difficult for anyone who is newish to linux to do an RVM installation using the provided instructions: https://rvm.io/rvm/install/ - the instructions are not very clear. They also recommend reading the installation script, which is long and scary: "I recommend you read the installation script yourself. This will give you a chance to understand what it is doing before installing, and allow you to feel more comfortable running it if you do so." ... https://github.com/wayneeseguin/rvm/blob/master/binscripts/r...

Amen. I just guided my manager through the install and only then realised how much of it was muscle memory for me. The script tells you to install XCode 4.1 because it doesn't work with 4.2... but XCode is up to 4.4 now, and I know 4.3 works because that's what I have installed! It also advises you to install "latest stable" but has references to 1.9.2 in several places... it is, overall, a mess.

I ran through installing RVM yesterday on a new Mac and it wasn't a problem - 10.8, XCode 4.4, homebrew (okay, you have to install XCode CLI and Quartz separately), but it ran right through it. Then again, this is one combination that I know to work, I've definitely had it get byzantine with other versions of XCode in the past.

I've found rbenv to be a much easier option with homebrew.
