Ruby 安装nokogiri 1.6.0时出错：未能生成gem本机扩展？

在我的Gemfile（它依赖于Nokogiri）中使用seleniumwebdriver~>2.35.1运行

bundle安装后，我遇到以下错误

我试着用命令行指定Nokogiri需要的两个本机库，但这似乎没有帮助

我也找不到“mkmf.log”文件或“configure.log”文件

我尝试并安装了Nokogiri 1.5.10。
可能的副本完全不可能在不了解环境细节的情况下回答。Nokogiri需要本地构建的特定库，并且它们必须位于特定的位置。libxml2是罪魁祸首之一。
Building native extensions with: '--with-xml2-lib=/usr/lib64 --with-xml2-include=/usr/include/libxml2 --with-xslt-lib=/usr/lib64 --with-xslt-include=/usr/include/libxslt'

This could take a while...
