Hi,

For me it turned out to be some problem with MacPorts, removing MacPorts (with all its installed ports) solved the problem regarding ZLib. I assume that a less drastic measure would also work (only remove selected ports or remove the ports from your path).

This specific error happens when you try to link with a 64-bit library from 32-bit GHC. So the odds are good either your flags aren't set right in /usr/bin/ghc and friends (which was an issue on 6.10), or you're linking to a non-universal copy of zlib (like the one macports will build).
