title: Could not find pg-0.17.1 in any of the sources
body: <p>I am trying to resolve this error but am unsuccessful and looked through some of the previous SO threads on this issue. </p>
  
  <p>'sudo apt-get install libpq-dev postgresql-devel' did not work as I dont have apt-get. I tried replacing apt-get with wget and that did not work either.</p>
  
  <p>I also tried the following but that did not work either and I got the error below</p>
  
  <p>export PATH=/usr/pgsql-9.3/bin:$PATH
  bundle install</p>
  
  <p>An error occurred while installing pg (0.17.1), and Bundler cannot continue.
  Make sure that <code>gem install pg -v '0.17.1'</code> succeeds before bundling.</p>
  
  <p>Can anyone advise? I am on a Mac OSx V9.10.5</p>
