To install virtualenv via pip
$ pip3 install virtualenv

Note that virtualenv installs to the python3 directory. For me it's:
$ /usr/local/share/python3/virtualenv

Create a virtualenvs directory to store all virtual environments
$ mkdir somewhere/virtualenvs

Make a new virtual environment with no packages

example use of pandas with oracle mysql postgresql sqlite
    - updated 9/18/2012 with better column name handling; couple of bug fixes.
    - used ~20 times for various ETL jobs.  Mostly MySQL, but some Oracle. 

    to do:  
            save/restore index (how to check table existence? just do select count(*)?), 
            finish odbc,
