Golang Dep Issue with yarpc-go & tchannel-go

[kevinguard]

Using yarpc for an open source project which uses golang/dep for dependency management, when issuing dep ensure -v, fetching process freezes as a result of the following error:

I don't think there's anything in TChannel that can be changed? The glide.yaml has reasonable version constraints for all dependencies, no branch/tag pins.

Is there a concrete action item for TChannel here?

@prashantv Had discussed about this in an internal thread and we have identified the root cause. We can safely close this. Thanks!
