Problem with "python bzr_set.py" for Openerp installation

When i try to download openerp with the command "python bzr_set.py", at the end of the downloading i receive this error:

Connection Timeout: disconnecting client after 300.0 seconds

IOError: [Errno 32] Broken pipe

and the consequence in Openerp is that i don't have all the modules i need.
