解决方案

错误信息（您必须先安装开发工具。）说明了一切。另外，您不必在Lion上安装第三方PostgreSQL，因为它已包含在内。

Postgres was downloaded and installed from http://www.postgresql.org/download/macosx/ (version 9.1)

I was trying to install postgres with brew - no results.

How to fix this ? Thanks

解决方案

The error message ("You have to install development tools first.") says it all. Install Xcode first, and then try installing the pg gem.

Also, you don't have to install a third-party PostgreSQL on Lion, as it's already included.
