  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.

  <p>I tried to uninstall postgresql using Homebrew and reinstall and that didn't help.</p>
  
  <p>I tried...</p>
  
  <pre><code>ARCHFLAGS="-arch x86_64" gem install pg
  </code></pre>
  
  <p>and that completes successfully but then when I run <code>bundle</code> I still get the same error.</p>
  
  <p>I tried ...</p>
  
  <pre><code>gem install pg -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config
  </code></pre>
  
  <p>and that didn't work.</p>
  
  <p>I tried ...</p>
  
  <pre><code>gem install pg -v '0.17.1' -- --with-pg-config=/usr/local/Cellar/postgresql/9.3.2/bin/pg_config
  </code></pre>
  
  <p>and that didn't work either.</p>
  
  <p>I am not sure what else to try at this point.
  Thanks for any help.</p>
