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
```

commit 42bf0dedba
Author: Bryan Boreham <bjboreham@gmail.com>
Date: Sat Sep 23 21:08:33 2017 +0000
Update ugorji/go/codec to latest commit 54210f4e076c57f351166f0ed60e67d3fca57a36
[...]
```
* Bump github.com/ugorji/go/codec, to get fixes which make
github.com/2opremio/go-1/codec unnecessary
* Remove github.com/2opremio/go-1/codec
* Remove type embeddings to avoid the problem explained at
https://github.com/ugorji/go/issues/141#issuecomment-185450157
This caused a dependency chain reaction (sigh):
* All the k8s packages had to be fetched again. This in turn required:
* Pining github.com/docker/docker/pkg/parsers to
0f5c9d301b9b1cca66b3ea0f9dec3b5317d3686d to cirvumvent
https://github.com/kubernetes/kubernetes/issues/18774
* Update github.com/juju/ratelimit
* Make probe/kubernetes/client.go comply with API changes.
