Mike,
don't go in site-packages at all, except for browsing and looking at
the source for information.

basic steps:

run installer
go to a working directory, not under the python directory in programs,
(and without any scipy, numpy source in it)
then start python or idle there
and then import numpy and scipy and test, that's it.

Unless there is a reason for you to change the numpy, scipy source
there is no reason for you to touch any of the config, compile build
steps. They are for later, when you need additional packages that
don't have an installer.

To get up and running, I recommend just to follow the basic steps for a user.
