The problems you are encountering with building Hat are largely due
to the newer version of ghc (6.0) you are using.  ghc-6.0 has some
API changes in its Exception library.  I have a workaround, but it
turns out that fixing this one problem reveals several more issues
with ghc-6.0, such as its stricter interpretation of some of the
lexical rules of Haskell'98.

I do hope to find workarounds for all of the ghc-6.0 compatibility
issues, but in the meantime, you may make better progress if you use
an earlier stable release of ghc such as 5.04.3 on MacOS X (assuming
such a beast exists).
