google-cloud-sdk @439.0.0: ERROR: Python 2 is not compatible with the Google Cloud SDK

[ryandesign (Ryan Carsten Schmidt)]

google-cloud-sdk doesn't build on Mojave or earlier:

​https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/198911/steps/install-port/logs/stdio

Welcome to the Google Cloud CLI!
ERROR: Python 2 is not compatible with the Google Cloud SDK. Please use Python version 3.5 and up.

If you have a compatible Python interpreter installed, you can use it by setting
the CLOUDSDK_PYTHON environment variable to point to it.

I don't have access to a Mac with Python 2, so I can't test it, but I hope that this PR causes MacPorts' Python 3 to be used to run the install script: ​https://github.com/macports/macports-ports/pull/19525

Thanks.
