Go links everything statically and the dependencies are just snapshots
of other git repositories. It is not possible to create ports for the
dependencies, as it might need exactly one tag or arbitrary commit of
the dependency. The glide.lock file can be used to determine the exact
revision/branch of the dependencies and generate a list of tarballs.
These would when be fetched and put into a temporary GOPATH/GOROOT (or
whatever it is called) to be used during build.

The peco port is already using this approach and I think it is the right
way to go foward. The snippets from that port should be turned into a
port group.

As an example, look at the cargo and cargo_fetch port groups that
implement dependencies for rust this way:
