"source" declaration not followed?

Dep version v0.1.0-236-g98f1d99

Attempting to work around #767. The following declaration feels like it should handle my situation (Gopkg.toml):

[[constraint]]
  name = "stvn.cc/broadcaster"
  source = "https://github.com/stvnrhodes/broadcaster.git"
  revision = "4d2a8f427f43c008b3e854b91e241196e23310b2"

However,

$ dep ensure
solve error: No versions of <redacted> met constraints:
	master: unable to deduce repository and source type for: "stvn.cc/broadcaster"
ensure Solve(): No versions of <redacted> met constraints:
	master: unable to deduce repository and source type for: "stvn.cc/broadcaster"

Should the source declaration not remove the need to talk to the (down) stvn.cc domain?

Attempting to do it explicitly results in roughly the same thing:

$ dep ensure stvn.cc/broadcaster:github.com/stvnrhodes/broadcaster@4d2a8f427f43c008b3e854b91e241196e23310b2
could not infer project root from dependency path: stvn.cc/broadcaster: unable to deduce repository and source type for: "stvn.cc/broadcaster"

$ dep ensure github.com/stvnrhodes/broadcaster:stvn.cc/broadcaster@4d2a8f427f43c008b3e854b91e241196e23310b2
solve error: No versions of <redacted> met constraints:
	master: unable to deduce repository and source type for: "stvn.cc/broadcaster"
ensure Solve(): No versions of <redacted> met constraints:
	master: unable to deduce repository and source type for: "stvn.cc/broadcaster"

There should be some way to say "grab this github repo into this import path" without the import path having to resolve?
