I have created a new user account on my mac and I am trying to update to the current version of ruby on it (1.9.2) from the snow leopard default of 1.8.7. Can somebody point
I'll make a strong suggestion for rvm.
It's a great way to manage multiple Rubies and gems sets without colliding with the system version.
I'll add that now (4/2/2013), I use rbenv a lot, because my needs are simple. RVM is great, but it's got a lot of capability I never need, so I have it on some machines and rbenv on my desktop and laptop. It's worth checking out both and seeing which works best for your needs.
