BTW buildout 1.7.1 exists, and should be compatible with 1.5.x.

Be sure you're using the latest version of pre-2.0 bootstrap.py by
downloading it from http:/downloads.buildout.org/1/bootstrap.py

Use a virtualenv to give both distribute and setuptools >= 0.7 to
buildout:

    virtualenv env
    env/bin/pip install -U setuptools
    env/bin/python bootstrap.py
    bin/buildout

This works with both buildout 1.x and 2.x.

helping of scorn and sarcasm) in return.
