There was another report on that issue, but we don't have a fix yet.
The version we are actually using is 7.4.1, and we had no problems.

Hake generates Hakefiles.hs, which is then evaluated, and this is where the
error happens. I remember hitting something similar before, but the details
elude me. I don't have a 7.4.2 ghc handy, so I can't reproduce it. Would it be
possible to try a 7.4.1 version of ghc?

If you plan to debug this, there is a discussion on the ghc list that might be
proven helpful:
