Difficulty bundling pg using Mac Postgres App

Question

I've tried bundling my Rails app on my Mac at work. At home it works fine and I've managed it solve it myself previously but this time no matter what I try nothing appears to be working to resolve it.

The error I receive when running bundle/bundle install is the following:

Installing pg (0.17.0) Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

/Users/notrab/.rbenv/versions/2.0.0-p0/bin/ruby extconf.rb

checking for pg_config... no No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config checking for libpq-fe.h... no Can't find the 'libpq-fe.h header * extconf.rb failed * 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.

Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/Users/notrab/.rbenv/versions/2.0.0-p0/bin/ruby --with-pg --without-pg --with-pg-config --without-pg-config --with-pg_config --without-pg_config --with-pg-dir --without-pg-dir --with-pg-include --without-pg-include=${pg-dir}/include --with-pg-lib --without-pg-lib=${pg-dir}/

Gem files will remain installed in /Users/notrab/Sites/Integrity/vendor/bundle/gems/pg-0.17.0 for inspection.

Results logged to /Users/notrab/Sites/Integrity/vendor/bundle/gems/pg-0.17.0/ext/gem_make.out

An error occurred while installing pg (0.17.0), and Bundler cannot continue. Make sure that gem install pg -v '0.17.0' succeeds before bundling.

I've obviously tried running

gem install pg -v '0.17.0' and it says it was successful but bundling again shows the same error.

I have also tried running

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config

Which is outlined in the documentation http://postgresapp.com/documentation but the same error occurs when I try to bundle.

I'm going round in circles and don't know how to resolve it.

My Gemfile looks like:

group :development, :test do
    gem "better_errors"
    gem 'meta_request'
    gem 'binding_of_caller'
    gem 'sqlite3'
end

group :production do
    gem 'pg'
end

Many thanks,

Jamie

Have you tried adding export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH" to your .bash_profile?
