I'm trying to install openobject-server on OSX 10.8.3.

I have done:

python setup.py build
sudo python setup.py install

Now when trying to start I get this error:

gizur-laptop-5:openobject-server jonas$ ./openerp-server --addons-path=~/home/workspace/stable/addons
Traceback (most recent call last):

Any suggestions are greatly appreciated.
