I think it's another issue, more related to the way easy_install or
pip works with PyPI
(using package_index.py)

once those scripts have a list of dependencies, they are looking for
it at PyPI using the simple index,
and download the "best pick", and binary releases for your platform
will come first.

So, for pyscopg, if this page : pypi.python.org/simple/psycopg

would contain the binary distribution for your platform, it would
work. but there's only the source release,
and the home url doesn't contain anything useful, so it grabs the
source version for your case.

zope.interface for example has binary releases for win32 so win32
users don't have to compile it:
pypi.python.org/simple/zope.interface
