bundle failing - Can't find the PostgreSQL client library (libpq) [duplicate]
Based on this post's answer and it worked for me (Yosemite OSX 10.10), you can try the following:
$ sudo su$ env ARCHFLAGS="-arch x86_64" gem install pg
You don't have to reinstall pg from homebrew.
sudo ARCHFLAGS="-arch x86_64" gem install pg
DID THE TRICK FOR ME...thanks for tip on a thread given by Jakob@github
