Ruby on Rails チュートリアル第3章の初っ端からbundle installができず、つまってしまった。

************************************************************************
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.

Complete!

Your bundle is complete!
Gems in the group production were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
Post-install message from capybara:
IMPORTANT! Some of the defaults have changed in Capybara 2.1. If you're experiencing failures,
please revert to the old behaviour by setting:

    Capybara.configure do |config|
      config.match = :one
      config.exact_options = true
      config.ignore_hidden_elements = true
      config.visible_text_only = true
    end

If you're migrating from Capybara 1.x, try:

    Capybara.configure do |config|
      config.match = :prefer_exact
      config.ignore_hidden_elements = false
    end

bundle installできた！

以前も同じようなエラーが出て、その時はXcodeのcommand line developer toolsをインストールしたら解決したんだが・・・。nokogiri問題について後で調べておきたい。
