After trying to install psycopg2 – a postgres adapter for python on Mac OS X. But seem the Xcode library has screwed the whole thing. Several methods I have tried with pip are all failed. So here a faster way, use MacPort to install.
1. Install MacPort if you don’t have
2. Install psycopg2 directly
sudo port install py27-psycopg2
3. Set up to use MacPort Python 2.7 if you already have Python 2.7 installed
sudo port select --set python python27
