Hi Mariano, Unfortunately there are quite a few things (MissingH being one of them) which have not yet been updated to work with GHC 7.2.1. Your options are (1) downgrade to GHC 7.0.4 for now, or (2) wait for MissingH etc. to be updated. You can possibly speed up (2) by sending a bug report to the maintainer of any package you find that doesn't work (to find the maintaner, look for the package on Hackage, e.g. http://hackage.haskell.org/package/MissingH, and look at the "Maintainer" field).
