Comment 2 for bug 370420

This is more than just a consistency thing. Because the WSGI script uses sys.path.extend it means that buildout-installed dependencies get overridden by system-wide packages, and this makes djangorecipe-based deployments hard or impossible in shared hosting situations.

As an example, my particular situation is a host with lxml 1.3 installed but a deployment that needs lxml 2.2. The 2.2 egg is installed just fine, but because the WSGI script extends the path the systemwide 1.3 egg is always loaded instead.
