Problem building hat with GHC 5.04

I'm getting the following error when trying to compile hat using GHC 5.04
on a machine running RedHat Linux 7.3:

# make
cd src/compiler98;     make HC=ghc hat-trans
make[1]: Entering directory `/tmp/hat-2.00/src/compiler98'
hmake -ghc  +CTS -package lang -CTS    -d /tmp/hat-2.00/targets/ix86-Linux/obj/compiler98 HatTrans

Stop - hmake dependency error.

make[1]: Leaving directory `/tmp/hat-2.00/src/compiler98'
make: *** [targets/ix86-Linux/hat-trans-ghc] Error 2

It seems to be looking for the GHC 5.02.3 libraries, but I have GHC 5.04
installed. I know the system requirements say that Hat can't interoperate
with 5.04, but does it not work to compile Hat as well?

Thanks,
Kirsten
