app runs fine with interpreter, but not under py2exe

[Doug Morse]

Hi Harald and C.L.P.,

Precision.py is part of the Numeric package.  AFAIKT, the problem is during
the module initialization.  The first lines of Precision.py are:

from multiarray import zeros
import string

typecodes = {'Character':'c', 'Integer':'1sil', 'UnsignedInteger':'bwu',
'Float':'fd', 'Complex':'FD'}

def _get_precisions(typecodes):
    lst = []
    for t in typecodes:
        lst.append( (zeros( (1,), t ).itemsize()*8, t) )   <-- Line 18
    return lst

def _fill_table(typecodes, table={}):
    for key, value in typecodes.items():
        table[key] = _get_precisions(value)
    return table

_code_table = _fill_table(typecodes)


I can't find any reason why line 18 is throwing a "data type not understood"
error.  It doesn't seem to have anything to do with dynamic importing, but I
can't be sure.  I would note that "zeros" is a built-in function found in the
"python dll" multiarray.pyd (in the Numeric module directory).

Thanks again,
Doug
