I revised the latest version (http://hackage.haskell.org/package/average/revisions/) to exclude GHC < 7.4 since Num was a subclass of Fractional then and that instance doesn't exist for Average a. A new release is only needed if you want to support older GHCs, otherwise please add a base >= 4.5 lower bound.
Seems this repo is out of date, forgot to push?
