I am still struggling with this issue.

Is there something in 2.7 that would break the PythonScripts model for
creating a new product?

I followed the exact instructions in the Readme.txt supplied in the source:

    "The easiest way to make modules available to Python scripts on 
    your site is to create a new directory in your Products directory
    containing an "__init__.py" file. At Zope startup time, this 
    "product" will be imported, and any module assertions you make
    in the __init__.py will take effect. Here's how to do it:

      o In your Products directory (either in lib/python of your 
        Zope installation or in the root of your Zope install,
        depending on your deployment model), create a new directory
        with a name like "GlobalModules".

      o In the new directory, create a file named "__init__.py".

      o Edit the __init__.py file, and add calls to the 'allow_module'
        function (located in the Products.PythonScripts.Utility module),
        passing the names of modules to be enabled for use by scripts.
        For example:

          # Global module assertions for Python scripts
          from Products.PythonScripts.Utility import allow_module

          allow_module('base64')
          allow_module('re')
          allow_module('DateTime.DateTime')

        This example adds the modules 'base64', 're' and the 'DateTime'
        module in the 'DateTime' package for use by Python scripts. Note
        that for packages (dotted names), each module in the package path
        will become available to script objects."


I create a directory in the Products directory named DSV. In that directory
I create a file:

__init__.py

with the following contents:

# Global module assertions for Python scripts
from Products.PythonScripts.Utility import allow_module
allow_module('DSV.DSV')


In the DSV directory I have a DSV.py containing the dsv code.



(as I did for 2.6 where it was successful) an attempt to import the module
results in:

I can't figure out what do or try next. Does the "__init__.py" need to have
something else in it? Does the whole mess have to sit somewhere else ( I
have tried the Products directory in the main Zope and in the instance to no
avail)?

Any assistance appreciated.
