Dep: "dep init" failes to import glide with an importpath to a remote subpackage

[michael-go]

given main.go:

package main

import "github.com/c9s/goprocinfo/linux"

func main() {
    linux.ReadStat("/proc/stat")
}

and glide.yaml:

package: demo
import:
- package: github.com/c9s/goprocinfo/linux

glide install works and creates glide.lock:

hash: fe4cb6bd2a948473e3fca37a298728aef1ffa50bd542157f2893fd78f56f5d08
updated: 2017-07-20T13:49:53.844798928+03:00
imports:
- name: github.com/c9s/goprocinfo
  version: b34328d6e0cd139894ea7347d2624ccf31fa3c58
  subpackages:
  - linux
testImports: []

however dep init fails.
I should mention that dep init does support importing remote subpackages (as it should https://golang.org/cmd/go/#hdr-Remote_import_paths), but seems that it gets confused by glide.yaml here

I stumbled upon this issue when playing with dep and trying to run dep init on a popular go repo https://github.com/bcicen/ctop

What version of Go (go version) and dep (git describe --tags) are you using?

go version: go1.8.3 linux/amd64
dep version: v0.1.0-236-g98f1d99

What dep command did you run?

dep init

What did you expect to see?

success

What did you see instead?

Importing configuration from glide. These are only initial constraints, and are further refined during the solve process.

    master: Could not introduce github.com/c9s/goprocinfo/linux@master, as its subpackage github.com/c9s/goprocinfo/linux does not contain usable Go code (*build.NoGoError).. (Package is required by (root).)

It seems like dep tries to fetch github.com/c9s/goprocinfo/linux url directly instead of fetching the actual repository url github.com/c9s/goprocinfo

This is the same root cause as #843. Thanks for the bug report!

@carolynvs It seem this bug is fixed (probably thanks to https://github.com/golang/dep/pull/1100)

Just tested on the example above and on an older revision of https://github.com/bcicen/ctop that failed for me when I opened this issue (8 days ago they moved to dep anyhow :smile: )

Thanks for the help finding fixed issues!
