[Python-modules-team] Bug#734299: Bug#734299: python-cffi's testsuite fails when run with python3.4

Hi Matthias (2014.01.05_20:06:38_+0200)
> this looks similiar to #707164, there tracked down to some virtualenv issue.

Yup, good assumption:

$ virtualenv -p python3.4 ve
Running virtualenv with interpreter /usr/bin/python3.4
Using base prefix '/usr'
New python executable in ve/bin/python3.4
Also creating executable in ve/bin/python
Failed to import the site module
Traceback (most recent call last):
  File "/tmp/ve/lib/python3.4/site.py", line 67, in <module>
    import os
  File "/tmp/ve/lib/python3.4/os.py", line 634, in <module>
    from _collections_abc import MutableMapping
ImportError: No module named '_collections_abc'
ERROR: The executable ve/bin/python3.4 is not functioning
ERROR: It thinks sys.prefix is '/tmp' (should be '/tmp/ve')
ERROR: virtualenv is not compatible with this system or executable

It appears to be fixed in 1.11 (although I haven't tried the cffi test suite
with that, yet)
