当我运行命令rake:install时，我收到以下错误消息：

WARNING: 'require 'rake/rdoctask'' is deprecated.  Please use 'require 'rdoc/task' (in RDoc 2.4.2+)' instead.

  ===========   WARNING   ===========

  You are building this extension on OS X without setting the 
  ARCHFLAGS environment variable, and pg_config wasn't found in 
  your PATH. If you are seeing this message, that means that the 
  build will probably fail.

  If it does, you can correct this by either including the path 
  to 'pg_config' in your PATH or setting the environment variable 
  ARCHFLAGS to '-arch <arch>' before building.

  For example:
  (in bash) $ export PATH=/opt/local/lib/postgresql84/bin:$PATH                  
            $ export ARCHFLAGS='-arch x86_64'
  (in tcsh) % set path = ( /opt/local/lib/postgresql84/bin $PATH )
            % setenv ARCHFLAGS '-arch x86_64'

  Then try building again.

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.

显然是pggem中的问题，但是当我检查我的应用程序中已安装的gem列表时，有* pg (0.13.2)

那么我还缺少什么？

上述问题的解决方案：

 1. export PATH=/Library/PostgreSQL/9.1/bin:$PATH
 2. export ARCHFLAGS='-arch x86_64'
 3. rake install
