I saw the exact same thing but it appeared to come and go as I made
minor tweaks to the setup, and could never figure out why I sometimes
got this error and sometimes did not.  I added nummaray to the
packages list.

Yep, this is mentioned in the comment header of setup.py for the gtk
example (and in the FAQ).  Still, it's easy to miss, as I spent about
15 minutes trying to figure out what was going wrong (it had been many
months since I wrote the example) before I read my own comment.  I
added a print reminder to setup.py.

Curious to know if this works for Andrea too.  It appears to work for
me with py2exe 0.5.4

Thanks, I've updated the examples on the site.

I also saw your comment on the py2exe matplotlib wiki.  I changed the
init method slightly -- could you test this on your setup to make sure
it works

    if sys.platform=='win32' and sys.frozen: 
    path = os.path.join(os.path.split(sys.path[0])[0], 'matplotlibdata') 
    if os.path.isdir(path):  return path 
    else:
        # Try again assuming sys.path[0] is a dir not a exe 
        path = os.path.join(sys.path[0], 'matplotlibdata') 
        if os.path.isdir(path): return path
    raise RuntimeError('Could not find the matplotlib data files')

Thanks,
