继续-无法找到“ appengine”软件包

Question

I have followed this guide in installing the AppEngine SDK. https://developers.google.com/appengine/docs/go/gettingstarted/introduction

I have originally installed Go 1.2 with Brew (on OSX). I've set my paths:

export GOPATH=$HOME/Documents/go
export PATH=$GOPATH/bin:$PATH
export PATH=$HOME/Documents/go/go_appengine:$PATH

I copy/pasted hello world app, and ran it with goapp serve. All good.

Now, as soon as I try to use appengine:

import (
    "appengine"
)

I get compile time error:

api.go:5:5: cannot find package "appengine" in any of:
    /usr/local/Cellar/go/1.2/libexec/src/pkg/appengine (from $GOROOT)
    /Users/jan/Documents/go/src/appengine (from $GOPATH)

The starting guide documentation doesn't say anything about this. It seems like the SDK has its own $GOPATH like dir with /src, /pkg and /bin. I assume I would have to manually switch the $GOPATH between SDK and native Go all the time, which doesn't make any sense and doesn't even work for me (as I mostly work on non-appengine stuff).

I am clearly doing something wrong here. What am I missing?

EDIT: It seems like the actual appengine server is compiling and running fine, however my entire setup is broken (testing, Vim...). Is there any workaround?

As provided by alpe1, the following lines solve the vim compiler go:

ln -s $APPENGINE_SDK/goroot/src/pkg/appengine $GOROOT/src/pkg/ 
ln -s $APPENGINE_SDK/goroot/src/pkg/appengine_internal $GOROOT/src/pkg/
mkdir -p $GOROOT/src/pkg/code.google.com/p/
ln -s $APPENGINE_SDK/goroot/src/pkg/code.google.com/p/goprotobuf
$GOROOT/src/pkg/code.google.com/p/

and I needed to update gocode lib-path (cf Options) to have the autocompletion for appengine:

gocode set lib-path "$APPENGINE_SDK/goroot/pkg/linux_amd64_appengine"
