Hmm, looks like you are building Hat 2.01 (from CVS), not 2.00.

Is it possible that there is an old Hat.o file hanging around, but
you have removed the corresponding Hat.hi file (with `make clean'
or similar?)  Look for
    /Volumes/Apps/Install/nhc/targets/powerpc-Darwin-6.1/obj/hatlib/nhc98/Hat.o
and delete it if you find it.

You are making Hat 2.01 inside the nhc98 tree, rather than Hat 2.00
from the separately downloaded stable version.  My guess is that,
in the CVS tree you did

    ./configure
    make		# build nhc98
    make install	# install nhc98
    make hat

The final step probably failed with 

    ..../script/hat-trans: Command not found

and you guessed you needed something like

    ./hat-configure
    make clean
    make hat

If you really want the CVS version of Hat, then I suggest you start again with

    make realclean
    ./configure		# configure nhc98 (but we don't need to re-build it)
    ./hat-configure	# configure Hat
    make hat
    ./hat-configure --install	# install Hat - do not use 'make install'.
