cabal install failure

[mwotton]

periodically checking HLearn out to see if it's buildable & usable yet :)

orb ➜  ~/projects/HLearn git:(373ec25) ✗ cabal install --only-dependencies --enable-optimization=2  --enable-shared -j --enable-tests && cabal configure --enable-tests --enable-optimization=2  --enable-shared

Dependency tree exhaustively searched.

Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.

this is on master~1 - have also tried master & the ghc7.10 branch.
