I may be missing the obvious, but don't recollect ever seeing a
version tag and couldn't find when I looked again just then.

Is this script mean't to be able to run on a command line or is
executing under mod_python itself?

The problem with trying to run a standalone script to determine
something about mod_python is that mod_python will not fully
load if not imported from within the context of an interpretor 
running under Apache. The best I have managed to come up with
as a guide to determining which version of mod_python is to
try and import the psp module and see what sort of import error
occurs. See the description in:


>From code running under mod_python itself, there are a few
subtle differences in member data present in the request object
which one can used to determine between 2.7 and 3.1. For

    if hasattr(req,"hlist"):
      # In mod_python 3.X have the req.hlist member.
      handler_root = req.hlist.directory

    elif hasattr(req,"get_dirs"):
      # In mod_python 2.X have the req.get_dirs() method.
      handler_root = req.get_dirs()["PythonHandler"]

Don't know if this helps or not.
