bedandbreakfast needing a release

I've got a library that needed some simple matrix computation, so I added the bedandbreakfast package. While my library builds fine on both 7.6 and 7.8, the last released version of that package won't build on 7.8. However, the current HUB was update a couple of weeks ago, and now builds on 7.8. Is there some way to capture that information in a cabal file? That if you're using GHC 7.8, you need bedandbreakfast >= 5.*, but for GHC7.6 you can use bedandbreakfast >= 4.*? I did send an email to the maintainer a little over a week ago asking if he could do a release, and haven't gotten either a reply or a release. Any suggestions on what I should do about releasing the updated version of my library?
