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 Fail: Can't find module IO in .

I know the system requirements say that Hat can't interoperate with 5.04, but does it not work to compile Hat as well?
