Comment (by basvandijk):

 Hi rwbarton, yes a `cabal sandbox init; cabal install hs-opencv-binding/;
 cabal install play/` should be all that's required to build manually.

 I removed the dependency on `lens` like you suggested and the problem
 remains as expected.

 Note that I'm linking against `opencv-3.0.0`.

 It's very likely this has something to do with static vs dynamic linking.
