app-engine-go not supported

[GoogleCodeExporter]

What steps will reproduce the problem?

I have installed both the Go App Engine SDK and the Google Cloud SDK. Since I 
found that the Cloud SDK also supports App Engine, I have configured my 
environment to use the Cloud SDK instead of the App Engine SDK.

My environment is the following (zsh on Arch Linux):

unset GOARCH
unset GOBIN
unset GOOS

export GOROOT="$APPENGINE_HOME/goroot"
export PATH="$PATH":"$GCLOUD_HOME/bin":"$GOROOT/bin"
export APPENGINE_DEV_APPSERVER="$GCLOUD_HOME/bin/dev_appserver.py"

Note that I had to use GOROOT from the App Engine SDK.

What is the expected output? What do you see instead?

When I ran goapp serve, I get the following stack trace:

ol'

The Cloud SDK knows about go runtime; what is the reason why goroot is not 
included?

Creating a symlink to the goroot directory from the App Engine SDK solves the 
problem.

What is the output of 'gcloud info'?

This is a known problem. Currently you need to download the App Engine SDK for 
Go directly from 
https://cloud.google.com/appengine/downloads#Google_App_Engine_SDK_for_Go.
