ruby - Nokogiri 1.5.9 gem 没有安装在 Mac OS X Mavericks 上？

Question

昨晚我的系统更新到 Maverick，现在我无法从我的 gemfile 安装 Nokogiri。它提示找不到 libxml2，但 Maverick 附带了 libxml2。我也试过了

brew install --development libxml2

和:

brew install --development libxslt

我仍然看到相同的错误消息。我已经在下面粘贴了错误消息，有人可以看一下并告诉我接下来应该尝试什么吗？

mapte:config-renderer mapte$  gem install nokogiri -v '1.5.9'

对我来说，我必须安装开发者工具:

  xcode-select --install

然后一定要打开xcode应用并接受许可。
我尝试从命令行执行此操作，但没有成功。
