When using a buildout builder in shiningpanda plugin, one of the steps which is executed is downloading zc.buildout from pypi.python.org.
Unfortunately when this is executed from behind a firewall which expects authentification, this does not work (see below)

The bootstrap.py script used in setting up the environment seem to provide several parameter (e.g. --download-base) for changing the download server to a local pypi server. Making these available as configuration parameter would help to solve the problem
