I have my oracle install in my env variables.

You need to ensure that an Oracle Client has been installed on your machine. The easiest is the Oracle Instant Client which you can get from here:

http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Follow the instructions at the bottom of the page. Make sure you have installed the "Basic" or "Basic Light" package as well as the "SDK" package. The "SDK" package is only required for building cx_Oracle.
