No. The DPH libraries for a particular GHC branch are only expected to work with that branch. The DPH libraries are tied to a particular version of GHC, because they depend so much on properties of the vectoriser. I've been using a dependency on the base package as a proxy for the GHC version number. If you bump the base package version then you'll need to make a ghc-7.6 branch for DPH, like you've been doing for the other libraries. The HEAD version of DPH might work with ghc-7.6 right now, but we don't expect it to in the future. Is that ok?
