If you are using Postgres.app on Mac, you may resolve this issue once and for all like this:

First gem uninstall pg, then edit your ~/.bash_profile or ~/.zshrc file or equivalent and add:

# PostgreSQL bin path
export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.4/bin

Then bundle install and gem install pg should both work as expected.
