zc.buildout stopped working: ImportError: No module named apport.fileutils

Question

I've been using buildout for quite a while now without any issue, in fact I did yesterday without any problems.

But as today all my projects fail to buildout. I tried on two different Ubuntu workstations with the same result.

This is the error I get:

Initializing zc.buildout
Debug: Downloading http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg
Traceback (most recent call last):

    import zc.buildout.easy_install

    from apport.fileutils import likely_packaged, get_recent_crashes
ImportError: No module named apport.fileutils

Original exception was:
Traceback (most recent call last):
  File "bootstrap.py", line 259, in <module>
    import zc.buildout.buildout
  File "/tmp/tmpNkVMXW/zc.buildout-2.0.0-py2.7.egg/zc/buildout/buildout.py", line 18, in <module>

    pkg_resources.Requirement.parse('distribute')
AttributeError: 'NoneType' object has no attribute 'location'

It complains that there's no module named apport.fileutils .. but I get no exception when I run python and import it:

from apport.fileutils import likely_packaged, get_recent_crashes

2.0.0 just got released. The old bootstrap.py is not compatible with 2.0.0 but downloads it by default. You can get the v2 bootstrap.py from here, or use the code below if you want to stick with the old version.

python bootstrap.py -v 1.7.0

edit: older versions of v1 bootstrap.py don't allow version forcing. The up-to-date version here does.
