Using Gurobi solver in the Enthought Canopy Editor on Linux - ipython

Question

I am currently working with Gurobi solver using python. Previously, I have just been using a mix of a text editor and the terminal to write and run my models but I am currently experimenting with using Enthought Canopy Editor. I have a model that is works when I run in in the terminal using python model.py but when I try doing%run model.py in Canopy's iPython shell I get:
%run /home/cdhagmann/Copy/Code_Env/Farmer/model.py
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
/home/cdhagmann/Canopy/appdata/canopy-1.0.1.1189.rh5-x86_64/lib/python2.7/site-packages/IPython/utils/py3compat.pyc in execfile(fname, *where)
181 else:
182 filename = fname

----> 1 from gurobipy import *
2 from data_IO import read_data,currency
3 import time

5 # Import model data
ImportError: No module named gurobipy
My guess is that the terminal and Canopy look for modules in different places but I don't know how to rectify it. I found this reference on the Gurobi group site about Enthought Canopy and Gurobi on OS X 10.8 but didn't know how much those instruction would differ from doing it on Linux and even what he meant about installing Gurobi in Canopy's site-packages.
UPDATE: Based on information found the first link I clicked on, I did in fact leave the boxed clicked making Canopy my default directory. You have to manually prepend the PATH variable, which I missed them saying that I had to do. So I did that. I now have Canopy's version of iPython running in my terminal (check by using sys.path); however, I get a huge list of errors when I try run python.

If the terminal is correctly configured for Canopy Python, then python in terminal and Canopy Python should be looking for modules in the same places. If during installation, you disabled "make Canopy be default Python", or if you have not restarted terminal since installation, then it won't automatically be configured correctly.
These articles should help you understand and configure:

If these articles do not suffice for you to solve this, then please report -- when you run python from terminal, what are these?
sys.prefix
sys.path
gurobipy.__file__
