Macには初めからrubyがインストールされていますが、最新のバージョンを入れたいのと、
複数のバージョンを入れたいのでrbenvを入れたいと思います。
rbenbはhomebrewで入れられます。
$ brew install rbenv
==> Downloading https://github.com/sstephenson/rbenv/archive/v0.4.0.tar.gz
######################################################################## 100.0%
==> Caveats
To use Homebrew's directories rather than ~/.rbenv add to your profile:
export RBENV_ROOT=/usr/local/var/rbenv
To enable shims and autocompletion add to your profile:
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
==> Summary
🍺 /usr/local/Cellar/rbenv/0.4.0: 31 files, 152K, built in 3 seconds
以下のコマンドを実行する。
$ echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
次にruby-buildを入れます。これもhomebrewで入ります。
$ brew install ruby-build

######################################################################## 100.0%
==> Pouring openssl-1.0.1g.mavericks.bottle.tar.gz
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.
Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.
The OpenSSL provided by OS X is too old for some software.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

次に関連するrbenv-gemset、rbenv-gem-rehash、readline、apple-gcc42をhomebrewで入れます。
$ brew install rbenv-gemset

patching file specifications/rbenv-gem-rehash-1.0.0.gemspec
==> Caveats
If the GEM_PATH environment variable is undefined, rbenv-gem-rehash must
first execute the gem env gempath command to retrieve RubyGems' default path
so that it can can append to the path rather than override it. This can take
a while--from a few hundred milliseconds on MRI to several seconds on
JRuby--so the default path for the current Ruby version is cached to the
filesystem the first time it is retrieved.

$ brew install readline

######################################################################## 100.0%
==> Pouring readline-6.2.4.mavericks.bottle.2.tar.gz
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.
OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/readline/lib
CPPFLAGS: -I/usr/local/opt/readline/include

NOTE:
This formula provides components that were removed from XCode in the 4.2
release. There is no reason to install this formula if you are using a
version of XCode prior to 4.2.
This formula contains compilers built from Apple's GCC sources, build
5666.3, available from:
http://opensource.apple.com/tarballs/gcc
All compilers have a `-4.2` suffix. A GFortran compiler is also included.

デフォルトで使うバージョンを変更します。
