[pypy-issue] [issue1476] apparent regression in import in py2.0 b2

[Ian Delaney]

New submission from Ian Delaney <della5 at iinet.com.au>:

on installing the pypy2.0 beta2, the troublesome test.py pulls a peculiar fail.

lxml-cffi-3.0.2 $ PYTHONPATH=src/ pypy-c2.0 test.py

    AttributeError: 'lxml.etree._Element' object has no attribute 'honking'

py2.7 doesn't have problem with it, and I'm sure with pypy2.0 beta 1 installed
it had no issue with import paths instead failing on the 3 vs 4 args issue in a
data structure 'struct.

./src/lxml/xslt.py imports from with '.includes import xslt'
but it doesn't.
