Comment (by simonpj):

 Can you make a standalone case?  At the moment I just get stuck.
  * The `storablevector` package you point to depends on `utility-ht` and
 `transformers`.
  * In turn `transformers` depends on `special-functors`
  * `special-functors` requires `base` < 2, and I don't have that, since
 base is now up to version 4.

 I'm sure that most of this clutter is irrelevant to the problem you have.
 The easy way to remove unnecessary dependencies is to make stub modules
 with definitions like
 {{{
  thingy :: Int -> Int
  thingy = error "urk"
 }}}
 and than you don't need a separate package to define `thingy`.
