Environment details

• OS type and version: ANY
• Python version: ANY
• pip version: ANY (or N/A)
• google-api-python-client version: 1.8.1

Steps to reproduce

1. Install 1.8.1
2. Attempt to compile Python app that uses googleapiclient to an executable

Expected results

executable compiles and runs as it did with 1.8.0 library

Actual results

executable compiles but fails at runtime with:

pkg_resources.DistributionNotFound: The 'google-api-python-client' distribution was not found and is required by the application

this is due to removing googleapiclient.version and replacing with:

https://github.com/googleapis/google-api-python-client/blob/master/googleapiclient/model.py#L36

these issues will also occur if the library was not installed via pip (e.g. just cloned into a sub directory of the script).
