I'm getting this with ghc 7.6.3:

```
src/Darcs/Repository/ApplyPatches.hs:34:8:
    Could not find module `Control.Monad.Except'
    Perhaps you meant
      Control.Monad.Base (needs flag -package transformers-base-0.4.3)
      Control.Monad.Morph (needs flag -package mmorph-1.0.4)
      Control.Monad.Cont (needs flag -package monads-tf-0.1.0.1)
    Use -v to see a list of the files searched for.
Failed to install darcs-2.11.0
```

It tried to build darcs with transformers-compat-0.4.0.3.

"ghc-pkg list" tells me I have mtl-2.1.2 and transformers-0.3.0.0 installed.
