I struggled with this, too.
Here's my makefile, which is now working:

  1 GCC = gcc
  2 CFLAGS += -I/usr/lib/ghc-6.12.3/include/ -g -fPIC
  3 
  4 HC      = ghc
  5 HC_OPTS = -cpp $(EXTRA_HC_OPTS)
  6 EXTRA_HC_OPTS = -package parsec
  7 HC_LOPTS = -no-hs-main -shared -package parsec
  8 #GHCOPTS := -prof -auto-all -caf-all
  9 
 10 HSRCS = AMIParse.hs AMIModel.hs ApplicativeParsec.hs
 11 CSRCS = ami_model.c ami_test.c
 12 SRCS  = $(HSRCS) $(CSRCS)
 13 OBJS = AMIParse.o  AMIModel.o  ami_model.o AMIModel_stub.o
ApplicativeParsec.o
 14 
 15 .SUFFIXES : .o .hs .hi .lhs .hc .s .c
 16 .PHONY : all depend rebuild clean
 17 
 18 all: ami_test
 19 
 20 ami_test: ami_test.o libami.so
 21         $(HC) -dynamic -o $@ -L. -lami ami_test.o
 22 
 23 libami.so : $(OBJS)
 24         rm -f $@
 25         $(HC) -o $@ $(HC_LOPTS) $^
 26 
 27 depend:
 28         $(HC) -M $(HC_OPTS) $(HSRCS)
 29 
 30 rebuild:
 31         $(MAKE) clean
 32         $(MAKE) all
 33 
 34 clean:
 35         rm -f *.hi *.o *.out ami_test *.so
 36 
 37 # Standard suffix rules
 38 .o.hi:
 39         @:
 40 
 41 .lhs.o:
 42         $(HC) -c $< $(HC_OPTS)
 43 
 44 .hs.o:
 45         $(HC) -c $< $(HC_OPTS)
 46 
 47 .o-boot.hi-boot:
 48         @:
 49 
 50 .lhs-boot.o-boot:
 51         $(HC) -c $< $(HC_OPTS)
 52 
 53 .hs-boot.o-boot:
 54         $(HC) -c $< $(HC_OPTS)
 55 
 56 # Individual cases
 57 AMIModel_stub.o: AMIModel.hs
 58         $(HC) -c $< $(HC_OPTS)
 59 
 60 # DO NOT DELETE: Beginning of Haskell dependencies
 61 ApplicativeParsec.o : ApplicativeParsec.hs
 62 AMIParse.o : AMIParse.hs
 63 AMIParse.o : ApplicativeParsec.hi
 64 AMIModel.o : AMIModel.hs
 65 AMIModel.o : AMIParse.hi
 66 # DO NOT DELETE: End of Haskell dependencies

Good luck!
