我有 OSX 10.6.8 并试图在我的设备上安装 PostgreSQL 9.2。我使用了他们网站上提供的图形安装程序，并设置了软件，最后没有使用堆栈构建器来额外配置其他功能。
当我加载 Rails 文件bundle install时遇到以下错误：

An error occurred while installing pg (0.15.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.15.1'` succeeds before bundling.
我已经尝试过gem install pg -- --with-pg-config=/Library/PostgreSQL/9.1/bin/pg_config，我得到的所有错误消息建议以及这里的解决方案。我还尝试重新安装 Postgres，找到适当的配置路径，并找到错误消息提到的 mfmk.log 文件（但该文件在我的计算机上不存在）。此外，在我的应用程序/PostgreSQL 下，有一个“重新加载配置”应用程序，当我运行时，它会显示Server signaled.
有谁知道我应该怎么做？我打算尝试 Homebrew，但我发现安装程序本身无法生成正常运行的软件很奇怪。
