Read this if your buildout stopped working right now (crash after Got astroid 1.3.7)

Hi,

https://pypi.python.org/pypi/astroid/1.3.7 (a dependency of pylint) was
released today (2015-07-27) and just break my buildouts which are using
https://raw.github.com/plone/buildout.jenkins/master/jenkins.cfg

Short version : To fix the problem, just pin logilab-common = 0.63.0 in
your versions.cfg

Long version :
The error is the following

Got astroid 1.3.7.
Traceback (most recent call last):
  File "bin/buildout", line 12, in <module>
    sys.exit(zc.buildout.buildout.main())
  File
"/var/lib/jenkins/.buildout/eggs/zc.buildout-2.2.1-py2.7.egg/zc/buildout/buildout.py",
line 1950, in main
    _doing()
  File
"/var/lib/jenkins/.buildout/eggs/zc.buildout-2.2.1-py2.7.egg/zc/buildout/buildout.py",
line 1687, in _doing
    message = str(v)

line 1304, in __str__
    existing_dist, req = self.err.args
ValueError: need more than 1 value to unpack

The error is hidden, this was fixed in zc.buildout 2.4.0. I upgraded my
toolchain to:
Products.GenericSetup =
1.7.6
setuptools =
18.0.1
zc.buildout =
2.4.0
zc.recipe.egg = 2.0.2

and the error is the following:

Updating jenkins-csslint.
Updating jenkins-utf8-header.
Updating jenkins-code-analysis.
Installing pylint.
While:
  Installing pylint.
Error: There is a version conflict.
We already have: logilab-common 1.0.2
but astroid 1.3.7 requires 'logilab-common<=0.63.0'.

With verbose mode (-vvvvv) I get this:
We have the best distribution that satisfies 'astroid>=1.3.6'.
Picked: astroid = 1.3.7
Getting required 'logilab-common>=0.53.0'
  required by pylint 1.4.4.
We have the best distribution that satisfies 'logilab-common>=0.53.0'.
Picked: logilab-common = 1.0.2
While:
  Installing pylint.
Error: There is a version conflict.
We already have: logilab-common 1.0.2
but astroid 1.3.7 requires 'logilab-common<=0.63.0'.

To fix the issue I pinned logilab-common = 0.63.0 in my versions.cfg
