pycassaShell keybindings arrows don't work ^[[A

Question

When in pycassaShell, If I press arrow keys to move the cursor, I see ^[[A to ^[[D characters appended, it doesn't happen with normal python console interpreter

nb:

Python 2.6.5, / Ubuntu 10.04 pycassa installed just now using http://pycassa.github.com/pycassa/installation.html and running first http://python-distribute.org/distribute_setup.py, without it, it complained

I have this warning when running pucassaShell:
[I]: IPython not found, falling back to default interpreter.
