MacOSX install problem

Dear Hugs-bugs:

Excuse me in advance if this is a known problem. I am new 
to Haskell and I am trying to install HUGS on a MacOSX 
10.3 system with gcc3.3. I get the following ld errors:

gcc  hugs.o edit.o observe.o builtin.o compiler.o errors.o 
evaluator.o ffi.o goal.o input.o machdep.o machine.o 
module.o opts.o output.o plugin.o script.o static.o 
storage.o strutil.o subst.o type.o version.o  -lncurses 
   -o hugs
ld: Undefined symbols:
_doubleFromParts
_part1Double
_part2Double

Any ideas for a workaround?
