That works great until something in the stack or system config isn't quite right. Moncef's script handles a bunch of the common failure states. I posted it because it saved a colleague a ton of time un-borking a homebrew ruby install earlier today.
That's great to hear! That situation is more common than people might think. My script is based on 10 years of helping people set up a proper dev environment on a Mac, and I've seen pretty much every error and scenario so far.
And the main reason to use the script is to save time, which is our most valuable and limited resource. The Prime version installs a lot more than just Ruby. You can set up a new Mac with all your favorite dev tools and Mac apps.
Imagine a growing company that builds Rails apps. What would be more efficient? To have every new engineer set up their machine manually on their own, or have them run a script that installs everything they would need?
