sorry marco I try reading it from next time and inquire you if facing a problem. Between I tried whlich gfortran which gave just no output then I tried sudo apt-get install gfortran and then tried which gfortran it returned exactly /usr/bin/fortran. I then tried configure again and found that it did recognize gfortran as the fortran compiler, but when I scanned through the configure log I found these lines that seem to be doing the problem:
configure:33371: checking for gfortran
configure:33387: found /usr/bin/gfortran
configure:33398: result: gfortran
configure:33424: checking for Fortran 77 compiler version
configure:33433: gfortran --version >&5
