Are you by chance mixing different gfortran versions? For instance g++ 
and one gfortran under /usr/bin and a newer gfortran under 
"/home/alberto/gfortran" (or wherever)?

That could explain the problems. Then g++ picks up 
/usr/lib/libgfortran.so* and gfortran picks up another libgfortran.

If that is the case, try -L <path to gfortran lib> -lgfortran.
