If it's a brew cask problem please file this issue at https://github.com/caskroom/homebrew-cask/issues/new. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• [ x ] Ran brew update and retried your prior step?

Formula additions or changes

To get formulae added or changed in Homebrew please file a Pull Request
We will close issues requesting formulae changes.

I attempted to change the autoconf formula but adding automake as a dependency causes a circular dependency. When I added the dependency I made it a run time dependency so it should be able to break the circular dependency.
