PackageLoader issues  If you get a message like
ImportError: cannot import name factorial (see or, this is due
to a failure in a somewhat-magical mechanism that Scipy uses to
import symbols into the top-level scipy module. Rather than,
e.g., from scipy.x.y import *, it uses a Numpy mechanism called
PackageLoader, which uses files in each submodule to know what
symbols to import. Those files do seem to be making it into the
py2exe distribution, but they're not getting used correctly. I'm
not sure if the bug is scipy or py2exe.  A hackish workaround is
to modify scipy/ to explicitly import the symbols you need,
e.g., from scipy.misc import factorial.  Brian K. Boonstra  The
problem  When using py2exe with scipy, you end with messages
about missing modules. Some of them may not end up mattering (as
in my case where scipy_base.add was missing) but others do,
notably __cvs_version__ modules of some scipy packages, plus the
cephes module.  The solution  You just need a few includes. Here
is what I have:  excludes =
