As an aside, this is not the best use of the PYTHONPATH
variable. (I would argue that, on Windows at least, there's very little
need for the env var).

In general, you'll want to be using a mechanism such as pip:

  http://pypi.python.org/pypi/pip

which will look things up on PyPI so you can just do "pip install
newmodule". This will install into c:\python27\lib\site-packages. The
same for a module you install "manually" (ie python setup.py install) or
via an .exe or an .msi from PyPI or elsewhere.

There are other possibilities: .pth files, the PYTHONPATH env var,
virtualenv, user-install directories which you can read about, but in
general, just let the standard mechanisms install into
c:\python27\lib\site-packages (which is automatically on sys.path) and
go from there.
