Hey John,
I get the following build error:
/usr/bin/ghc -fbang-patterns -O -ignore-package lang -W
-fno-warn-unused-matches -fwarn-type-defaults -i -i./drift_processed -i./.

Util/Gen.hs:6:7:
Could not find module `Control.Monad.Identity':
it was found in multiple packages: transformers-0.1.1.0 mtl-1.1.0.2
make[1]: *** [jhc] Error 1
I *think* you have to -hide-all-packages then enable the ones you want
one-by-one (check whatever
commandline cabal emits here).
Cheers,
Don
