Yes, that is the reason why the configure script fails, and Olli's
patch will get you past this stage. However, with the hat-2.02
distribution you will encounter many more small incompatibilities
with ghc-6.2, which may prevent you from building successfully.
Various packagers (e.g. debian) have already worked around all of
these minor problems for ghc-6.2, and indeed the CVS repository also
contains these necessary fixes. We hope to release a new version,
hat-2.04, in the near future to address the issue, but of course
there are various other enhancements we would like to add too, and
polishing those takes time. In the meantime, I suggest you take one
of the following courses of action:
* downgrade ghc to 5.04.3
* or use a pre-packaged distribution for ghc-6.2 (e.g. debian)
* or build from the anonymous CVS archive at cvs.haskell.org
