That's a tricky question. We are currently working on getting DPH to work properly with GHC 7 but we aren't quite done yet. You might want to try 7.0.1 + the DPH sources from the darcs repo.

Nowadays, you have to install DPH separately which isn't easy since we haven't released the packages yet. In any case, DPH doesn't work with the current HEAD at all because I haven't adapted it to the new superclass story yet.
