Dear Airflow Maintainers,

After install from pypi using pip：
pip install airflow
I am trying to initialize the database：
airflow initdb
but I get this error：

Please copy paste your airflow.cfg

Psqlite2 has been long time renamed to sqlite3 when it became part of Python. You seem to have some very old versions lying around?

My system is centos6.5 and the python originally come with is 2.6.6. And I noticed the airflow is tested under python2.7.* ,so I install the python2.7.10

[henryon]

thought you should find "_sqlite3.so" right? @xu-xiaoqiang
