The 2.02 release of Hat is quite old now and does not compile
with ghc-6.x.  The CVS version works with all versions of ghc from
5.04.3 upwards.  We do plan to make a new release from CVS at some
point, but, as always, there are many other changes we would like
to incorporate before that happens.  In the meantime, compiling from
CVS is probably your best route to a working Hat.

OK, it looks like we are missing a ghc package dependency on the original
Haskell'98 libraries.  Try adding the arguments
    -package haskell98
to the HMAKEFLAGS at the top of src/hattools/Makefile.
