Hi Letizia,

your problem (maybe) is that you mix up different versions of compilers. gcc 
4.1.1 normally comes with gfortran 4.1.1 and not with g77 3.2.3. You now do have 
two possibilities:

Either deinstall your g77 package so that ./configure of octave finds gfortran 
4.1.1 or you do at least

  export F77=gfortran
  ./configure

This should help, otherwise please contact again.
