    from gcloud import datastore, logging
ImportError: No module named gcloud

The app.yaml file:

    runtime: python27
    api_version: 1
    threadsafe: true

handlers: 
- url: /
  script: main
  login: admin

The cron.yaml file:

 cron:
    - description: run main app
      url: /
      target: main
      schedule: every 2 minutes

the requirements.txt file:

   gcloud==0.14.0

Got it working! Use path:

import sys
sys.path.insert(0, 'lib')

Additional:
Also need to add protobuf in requirements: protobuf==3.1.0.post1

create __init__.py in google folder:

# this is a namespace package
try:
    import pkg_resources
    pkg_resources.declare_namespace(__name__)
except ImportError:
    import pkgutil
    __path__ = pkgutil.extend_path(__path__, __name__)

also use pip install -t lib --upgrade protobuf

gcloud==0.18.1 used.

Sorry for the late post
