Hmmmm, my email post doesn't seem to be showing up, so I'm going to
try it through the web, this will probably end up being a re-post :)

Hi Brad,

This is a conflict with package names.  Our packages are
google.appengine, and you are trying to use a packaged named
google.protobuf.

You should include the google.protobuf files in your application's
source directory, but you need to do a bit of sys.modules magic to get
it to work.

First, make a file called import_fixer.py.  The contents should be:

import os
import sys

BASE_PACKAGE = 'google'

def FixImports(*packages):


  topdir = os.path.dirname(__file__)
  def ImportPackage(full_package):
    """Import a fully qualified package."""
    imported_module = __import__(full_package, globals(), locals())

    # Check if the override path already exists for the module; if it
does,

    # that means we've already fixed imports.
    original_module = sys.modules[full_package]
    lib_path = os.path.join(topdir, full_package.replace('.', '/'))

    if lib_path not in original_module.__path__:
    # Insert after runtime path, but before anything else
      original_module.__path__.insert(1, lib_path)

  ImportPackage(BASE_PACKAGE)

  for package in packages:
  # For each package, we need to import all of its parent packages.
    dirs = package.split('.')
    full_package = BASE_PACKAGE
    for my_dir in dirs:
      full_package = '%s.%s' % (full_package, my_dir)
      ImportPackage(full_package)

~~~

Then, in your application file, do the following after importing all
your appengine modules:

import import_fixer
import_fixer.FixImports('protobuf')

from google.protobuf import descriptor

Then your imports should work.
