ipython style tab complete with ipdb for imported modules - ipython

Question

I'm trying to get ipython style table complete with pdb by using ipdb.
On a clean ubuntu 14.04 install (new aws instance) I run.
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install python-setuptools
sudo easy_install pip
sudo pip install ipython
sudo pip install ipdb
sudo pip install boto
Then boot up ipython, and try.
ubuntu#ip-10-0-0-244:~$ ipython

boto.[tab] just sits there. If I'm reading the docs right this should work, but maybe I have miss-understood something.
If I define a simple script test.py
import boto
print(boto.__version__)
Then call:
ubuntu#ip-10-0-0-244:~$ python -m ipdb test.py
> /home/ubuntu/test.py(1)<module>()
----> 1 import boto
2
3 print(boto.__version__)
ipdb> n
> /home/ubuntu/test.py(3)<module>()
1 import boto
2
----> 3 print(boto.__version__)
ipdb> boto.

I get the behavior I'd like.
Does anyone know how to make the tab complete functionality work for the set_trace() work case?
-Thanks
