makefile not working with c++ zkcm-library - can't find mpfr-functions

I have a makefile for use with some programs using the zkcm-library, including the following object line: 

zkcm_c.o: zkcm_c.cpp zkcm_c.h config.h
     g++ -c zkcm_c.cpp -lgmp -lgmpxx -lmpfr

The compiler complains that there is an "undefined reference to '_imp_mpfr__inits2' " and the same for every use of mpfr-functions. The strange thing is, there are other objects in the makefile that uses mpfr-functions with no problem, e.g. the main program (first line):

SpMC: SpMC.cpp MCutility.h HPutility.h wfs.h MC_funcs.h $(ZKCMOBJECTS)  $(ZKCMHFILES)
     g++ SpMC.cpp -lgmp -lmpfr -lmpc -o SpMC $(ZKCMOBJECTS)

In both cases I have #include<mpfr.h> in the source and as you see link to it using -lmpfr. Any ideas why this works for SpMC.cpp but not zkcm_c.cpp?
