while I update the module list, it gives "ImportError: No module named geraldo.utils"

I have tried the code:

$ cd

$ git clone https://github.com/CubicERP/geraldo

$ sudo easy_install Geraldo

$ cd /usr/local/lib/python2.7/dist-packages/Geraldo-0.4.17-py2.7.egg

$ sudo mv geraldo geraldo.bk

$ sudo ln -s ~/geraldo/geraldo geraldo

and it still give the same error, is there anything that I need to install?
