If you install the monads-fd package (with cabal install for instance), then you can no longer build git-annex:

<pre>
./configure
  checking cp -a... yes
  checking cp -p... yes
  checking cp --reflink=auto... yes
  checking uuid generator... uuid
  checking xargs -0... yes
  checking rsync... yes
ghc -O2 -Wall --make git-annex

Annex.hs:22:7:
    Ambiguous module name `Control.Monad.State':
      it was found in multiple packages: monads-fd-0.2.0.0 mtl-2.0.1.0
make: *** [git-annex] Error 1
</pre>
