This is due to a change in how FFI imports and newtypes work. GHC was recently changed to not allow you to use newtypes in FFI imports unless the constructor of the newtype is in scope. This broke quite a few libraries. I have patched a few of them and I've sent a patch to the zlib maintainer.
This seems like a big change. Where should I be watching to know about this ahead of time? I bet I have to fix some of my packages.
I suppose it will be in the release notes. I saw it on the GHC mailing list. -- Johan\
