Dear Sergio,
The routine zzfft is only used when SGIFFT is defined. Hence I think you
used the wrong system configuration when running ./configure.
What system did you select?
You should have chosen:
./configure linux64_opteron pgf90 lam pubfft
Substitute lam for whatever mpi you are using.
All the best
Ross
