With 6.12.1, you'll probably have an mtl-1.* installed, so the MonadIO used by MonadRandom is not the same as the one provided by transformers. Reinstall mtl to get version 2.* and MonadRandom if that's the case. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
