As of https://github.com/Homebrew/homebrew-core/commit/390173e Elasticsearch 1.7 can't be installed through Homebrew anymore. This mainly just requires updating the setup instructions for now since the bundle's dependencies require an ES 1.7 instance.
On a side note though, FOSElasticaBundle now has a 4.0 release supporting ES 2. So it'd be cool if the bundle could be updated to work with that (FWIW I have a quick hackjob at https://github.com/Lakion/SyliusElasticSearchBundle/compare/master...mbabker:FOSElasticaBundle-4-Support to get things running for one of my projects, though since we didn't use the search interface but rolled our own instead to tie in with our global search I'm not yet sure how much additional effort it would take to finish that upgrade up).
