Gem files will remain installed in /root/.rvm/gems/ruby-2.0.0-p353@rails4/gems/pg-0.17.1 for inspection.
Results logged to /root/.rvm/gems/ruby-2.0.0-p353@rails4/extensions/x86_64-linux/2.0.0/pg-0.17.1/gem_make.out
An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.
I couldn't locate the mkmf.log file mentioned.
我找不到提到的 mkmf.log 文件。

You need the Postgresql development libraries.
您需要 Postgresql 开发库。
Try:
尝试：
yum install postgresql-devel
or whatever is specific to your OS.
或任何特定于您的操作系统。
