Hi Colin, 

Sorry for the delay in getting back to you.  I just started playing
with py2exe.  I have an app that uses matplotlib that I would like to
freeze as well, so may as well take the plunge.

I found I could freeze a simple plot with 

    # setup.py
    from distutils.core import setup
    import glob
    import py2exe

    data = glob.glob(r'C:\Python23\share\matplotlib\*')
    data.append(r'C:\Python23\share\matplotlib\.matplotlibrc')

    setup(console=["simple_plot.py"],
          data_files=[("share",data)],
          )

where simple_plot.py is

    from matplotlib.matlab import *
    plot([1,2,3])
    show()

I also got a similar warning message at the end like you about "The
following modules appear to be missing" but it appears to be harmless.

A simple_plot.exe was created in my dist dir, as were a number of dlls
and the matplotlib share data dir.  I had to set the MATPLOTLIB env
var to point to the share dir, ie

  set MATPLOTLIBDATA=c:\python\jdh\py2exe\simple_plot\dist\share

but then it (partly) worked.  TkAgg and WXAgg worked out of the box (I
could change the default backend in the rc file).  Plain vanilla WX
behaved strangely: The WX frame with navigation bars etc popped up but
no graph.  I could click 'save' and save the graph to a jpeg which
viewed correctly.  But no image in the wx frame.  Hmm.  Haven't gotten
GTK* working yet.

Are you using the latest py2exe?  Notably, I didn't get the gtk dll
error when I left out the excludes.
