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%

==> 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

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.

homebrewのインストールが終わった状態はこんな感じです。

ではrubyのバージョンをあげたいと思います。
まずは今のバージョンがこちら。

バージョン2.1.1を入れてみます。
$ rbenv install 2.1.1 Downloading yaml-0.1.6.tar.gz... -> http://dqw8nmjcqpjn7.cloudfront.net/5fe00cda18ca5daeb43762b80c38e06e Installing yaml-0.1.6...

まだこの段階ではバージョンは変わっていません。
$ ruby -v ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]
選べるrubyのバージョンを確認すると、まだ初期から入っているrubyが使われています。
$ rbenv versions * system (set by /Users/xxxx/.rbenv/version) 2.1.1
デフォルトで使うバージョンを変更します。
$ rbenv global 2.1.1 $ rbenv versions system * 2.1.1 (set by /Users/xxxx/.rbenv/version)
あれ、変わりません。。。
$ ruby -v ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]
ログアウトしてコンソール立ち上げ直して再度やったらバージョン変わりました。
$ ruby -v ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]
