bundleで入れようとしてエラーではまったときにやった対応です。
まずはGemfileを書いて、bundle installを実行。
# /opt/sample/ruby/bin/bundle install --path vendor/bundle

************************************************************************
IMPORTANT! Nokogiri builds and uses a packaged version of libxml2.
If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall nokogiri as
follows:
gem install nokogiri -- --use-system-libraries
If you are using Bundler, tell it to use the option:
bundle config build.nokogiri --use-system-libraries
bundle install
However, note that nokogiri does not necessarily support all versions
of libxml2.
For example, libxml2-2.9.0 and higher are currently known to be broken
and thus unsupported by nokogiri, due to compatibility problems and
XPath optimization bugs.

An error occurred while installing mysql2 (0.3.16), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.16'` succeeds before bundling.
nokogiriもいろいろエラー出てるけど、とりあえずインストールできているので今回はスルー。mysql2がインストールできずにエラーになりました。
エラー内容を見てみると、`gem install mysql2 -v '0.3.16'`を実行してみろって書いてあります。
で実行してみたところ、やはりエラーとなります。
さらにエラー内容を見ていったところ、
「ld はステータス 1 で終了しました」というメッセージが出ています。
どうやらldでlibmysqlclientが見れてないようです。
libmysqlclientが実際に存在してないのかを確認します。
入れてあるRPMはこんな感じ。（RPMは独自に用意したものですが、名前通りのものをインストールしてます。）

libmysqlclient.soが存在してないですね。

調べていくと、インストールされている「MySQL-shared-compat.x86_64」はmysqlの旧バージョンと接続するためのもので、
MySQL5.6からは「MySQL-shared.x86_64」を入れないといけないようです。
ということで入れてみました。
# yum list installed|grep MySQL MySQL-client.x86_64 5.6.14-1.el6 @sample MySQL-devel.x86_64 5.6.14-1.el6 @sample MySQL-shared.x86_64 5.6.14-1.el6 @sample MySQL-shared-compat.x86_64 5.6.14-1.el6 @sample perl-DBD-MySQL.x86_64 4.013-3.el6 @base
そして、再度bundle installを実行。

gemだけでは完結しないので、ちゃんと構築しないといけないですね。
