Can't use 'auth' argument with connect()

[liftoff]

This works fine (ipython output):

In [1]: conn = xcffib.connect(display=':1')

This does not (as you can see):

In [2]: conn = xcffib.connect(display=':1', auth='NAME:binary-data')
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-2-3c6279d4cecc> in <module>()
----> 1 conn = xcffib.connect(display=':1', auth='NAME:binary-data')

/usr/local/lib/python2.7/dist-packages/xcffib/__init__.pyc in __init__(self, display, fd, auth)
    382         if auth is not None:
    383             c_auth = ffi.new("xcb_auth_info_t *")
--> 384             if C.xpyb_parse_auth(auth, len(auth), c_auth) < 0:
    385                 raise XcffibException("invalid xauth")
    386         else:

AttributeError: 'FFILibrary' object has no attribute 'xpyb_parse_auth'

I'm running Ubuntu 14.04 and I believe my xcffib installation went well (no errors).

Excellent!
