brew.sh: Install ruby-build and rbenv

[seanknox]

Hi there!

Boxen maintainer who complained about Puppet here! :) I'm digging dev-setup. Wanted to propose using rbenv/ruby-build to manage Ruby versions and installing them by default.

As managing gemsets isn't a common problems these days thanks to Bundler, rbenv and chruby have emerged as the de facto Ruby version managers used in the Ruby community. I've heard good things about chruby but haven't used it myself, yet.

I think rbenv is nicely aligned with the dev-setup philosophy, in that it's easy to install and does one and only thing really well, which is manage Ruby versions. Other pros:

• Lightweight; entire repo is < 900K
• Installs via Homebrew
• No configuration files ala RVM
• Doesn't override shell environment (it simply appends $PATH with additional rbenv directories)
• Uses ruby-build to download and compile Ruby on UNIX-like systems

@seanknox lol, great to meet you.

Thanks for the feedback and the contribution! I'm not familiar with rbenv, I'll read up on it and try to touch base with you by the end of the week. I guess technically this is your second contribution, you indirectly helped write the repo Boxen discussion :)

ruby-build and rbenv look like great tools. I haven't done much Ruby dev lately, thanks for helping me get caught up and for the contribution. 👍
