ERROR At installing the erpnext app in new site

Hello,

Currently, I have cloned the hotfix branch of erpnext.
Now I install the erpnext app in the new site but it gives me an error.

Traceback:

ImportError: Module import failed for POS Profile (erpnext.accounts.doctype.pos_profile.pos_profile Error: No module named address.address)

Have you updated frappe to latest version. ERPNext hotfix branch needs latest version of frappe.
