【问题描述】：
我正在运行OSX 10.8.2，Xcode 安装了命令行工具。
我正在尝试捆绑，并且在一些宝石上（我将在底部指定）我得到以下内容：
ERROR: Failed to build gem native extension
...
Could not create Makefile due to some reason
到目前为止，我在gem 'pg' 和gem 'binding_of_caller' 上遇到了错误
我认为该错误与无法创建 Makefile 有关，但找不到任何有助于解决该错误的内容。我在下面粘贴了完整的错误：
我不知道该怎么办。
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Gem files will remain installed in /Users/ericavirtue/.bundler/tmp/75812/gems/pg-0.14.1 for inspection.
Results logged to /Users/ericavirtue/.bundler/tmp/75812/gems/pg-0.14.1/ext/gem_make.out
An error occurred while installing pg (0.14.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.14.1'` succeeds before bundling.
编辑：我正在使用 rbenv 管理 ruby 版本，它说我正在运行 1.9.3 -p385系统 ruby 是旧版本，但据我所知，这不重要。
我通过homebrew 安装了postgresql
编辑 2：
我尝试切换到 RVM 进行 ruby 管理，但又出现了一个 make 错误：
Error running 'make -j2', please read ... ruby-1.9.3-p385/make.log
There has been an error while running make. Halting the installation.
文件make.log不存在...
