Not sure what happened, but `gvt` is most likely buggy.
Indeed, if you try to remove `ugorji/go/codec` and pull it again, with the revision listed in `vendor/manifest`, i.e.:
```
$ gvt delete github.com/ugorji/go/codec
$ gvt fetch --revision c062049c1793b01a3cc3fe786108edabbaf7756b github.com/ugorji/go/codec
YYYY/MM/DD HH:mm:SS Fetching: github.com/ugorji/go/codec
```
you then get the below build errors:
```
report/latest_map_generated.go:245:27: r.DecodeStringAsBytes undefined (type codec.decDriver has no field or method DecodeStringAsBytes)
report/latest_map_generated.go:497:27: r.DecodeStringAsBytes undefined (type codec.decDriver has no field or method DecodeStringAsBytes)

report/report.codecgen.go:1858:14: too many errors

```
which I also got in another project importing Scope.
This is fixed by running the following:
```
$ gvt delete github.com/ugorji/go/codec
$ gvt fetch --revision 54210f4e076c57f351166f0ed60e67d3fca57a36 github.com/ugorji/go/codec
YYYY/MM/DD HH:mm:SS Fetching: github.com/ugorji/go/codec
```

Weave Scope - Troubleshooting & Monitoring for Docker & Kubernetes
Weave Scope automatically generates a map of your application, enabling you to intuitively understand, monitor, and control your containerized, microservices based application.
Understand your Docker containers in real-time
Choose an overview of your container infrastructure, or focus on a specific microservice. Easily identify and correct issues to ensure the stability and performance of your containerized applications.
Contextual details and deep linking
View contextual metrics, tags and metadata for your containers. Effortlessly navigate between processes inside your container to hosts your containers run on, arranged in expandable, sortable tables. Easily find the container using the most CPU or memory for a given host or service.
Interact with and manage containers
Interact with your containers directly: pause, restart and stop containers. Launch a command line. All without leaving the scope browser window.
Extend and customize via plugins
Add custom details or interactions for your hosts, containers and/or processes by creating Scope plugins; or just choose from some that others have already written at the Github Weaveworks Scope Plugins organization.
Getting started
sudo curl -L git.io/scope -o /usr/local/bin/scope
sudo chmod a+x /usr/local/bin/scope
scope launch
This script downloads and runs a recent Scope image from Docker Hub.
Now, open your web browser to http://localhost:4040. (If you're using
boot2docker, replace localhost with the output of boot2docker ip.)
For instructions on installing Scope on Kubernetes, DCOS or ECS, see the docs.
