If you're looking for a Heroku buildpack to install your dependencies and build your binary I'm not aware of one. But, that would be a useful idea. Even something that could be used for Cloud Foundry as well.

On a build machine you'd do a `glide install` to get the dependencies installed, set the gopath (there are a couple ways to do it), and then go build per usual.

From there you can deploy the binary as needed.
