I have fixed these errors in svn.

Now I get

   File "/usr/local/lib/python2.4/site-packages/numpy/core/numerictypes.py", line 
85, in ?
     from multiarray import typeinfo, ndarray, array, empty
ImportError: cannot import name typeinfo

I checked that given multiarray comes from Numeric. It looks like freeze 
is not able to freeze extension modules that are not in path.
