At the PyCon sprints Jim and I were working with easy_install and working_env under Windows and noticed some odd behavior. When within an activated working environment, attempting to do something like:

attempts to retrieve the source distribution rather than the available Windows binary egg for PyPI.

What windows binary egg for PyPI? If you mean the one for 1.1, the problem is that easy_install isn't reading that page, because it's a "hidden" version. See:

Is this the expected behavior? I would have expected easy_install to prefer binary eggs.

It only prefers what it finds, and currently it won't find Cheeseshop files for "hidden" versions of a pacakge unless you include a -f to that page, e.g. -f http://cheeseshop.python.org/pypi/lxml/1.1 in this case.
