vagrant provision fails if pip setuptools < 17.1 in /vagrant

[dmccue]

Args:
vagrant provision

Symptoms:
==> default: Ran /vagrant/jenkins/share/eutester-base/bin/pip install --pre eutester returned 1
==> default: [2015-08-13T13:26:33+00:00] FATAL: Chef::Exceptions::ChildConvergeError: Chef run process exited unsuccessfully (exit code 1)

Reason:
==> default: Downloading/unpacking mock (from eutester)
==> default: Running setup.py egg_info for package mock
==> default: mock requires setuptools>=17.1. Aborting installation
==> default: Complete output from command python setup.py egg_info:
==> default: mock requires setuptools>=17.1. Aborting installation

[root@ip-10-112-26-206 ~]# /vagrant/jenkins/share/eutester-base/bin/pip list | grep setuptools
setuptools (0.9.8)

Solution:
/vagrant/jenkins/share/eutester-base/bin/pip install --upgrade setuptools

This could be done manually but each 'vagrant provision' erases the previous alterations as it overwrites everything in /vagrant.
Can whatever creates /vagrant/jenkins/share/eutester-base/bin/pip (possibly cookbooks/micro-qa/recipes/eutester.rb) be adjusted so that it updates setuptools immediately afterwards?
