How do I work around "AttributeError: can't set attribute" with zigbee.py?

Python
,

#!/usr/bin/python

import socket
import serial
import zigbee

#crashes here
sd = socket.socket(socket.AF_XBEE, socket.SOCK_DGRAM, socket.XBS_PROT_APS)

DESTINATION = ("[00:00:00:00:00:00:10:10]!", 0xe8, 0xc105, 0x11)

sd.bind(("", 0xe8, 0, 0))

sd.sendto("Hello, World!", 0, DESTINATION)

Traceback (most recent call last):
  File "./test.py", line 11, in 
    sd = socket.socket(socket.AF_XBEE, socket.SOCK_DGRAM, socket.XBS_PROT_APS)
  File "/home/pi/xbee/zigbee.py", line 1522, in __init__
    self.__xb_init(family, type, proto, xbee)
  File "/home/pi/xbee/zigbee.py", line 1528, in __xb_init
    self.family = family
AttributeError: can't set attribute

I’m attempting this on a RasPi B+ running Raspbian wheezy. For some reason the library seems to be trying to override socket.family, socket.type, and socket.proto, which are defined as read-only in the documentation for sockets.

Does anyone know how to prevent this from happening?
