First, try to get a shared version of FFTW.

If you can't do that:

1. Change lib/gmath/Makefile:

-EXTRA_LIBS=$(GISLIB) $(FFTWLIB) $(LAPACKLIB) $(BLASLIB)
+EXTRA_LIBS=$(GISLIB) $(LAPACKLIB) $(BLASLIB)

2. Change include/Make/Grass.make.in (and Grass.make if it already exists):

-GMATHLIB      = -l$(GMATH_LIBNAME) $(GISLIB) 
+GMATHLIB      = -l$(GMATH_LIBNAME) $(GISLIB) $(FFTWLIB) 

3. Re-compile.
