Seems like this commit:

broke the installation of that tap. In order to provide external commands (like `brew bundle`) Homebrew expects a file `brew-bundle.rb`, which has been deleted from the repo (or renamed `bundle.rb`

From this issue: [Unknown command: bundle · Issue #646 · Homebrew/homebrew-bundle · GitHub](https://github.com/Homebrew/homebrew-bundle/issues/646) it seems like `brew update` might fix the issue. Would be nice if the Travis team could update the build image, rather than requiring us to run `brew update` on every build. As you note in your docs:

> By default, the Homebrew addon will not run `brew update` before installing packages. `brew update` can take a long time and slow down your builds.

edit: confirming that adding `update: true` fixes my build.

```auto
    addons:
      homebrew:
        packages:
        - graphicsmagick
        update: true

```
