Howdy Tiago,

There are two problems here. The easy one is the problem of the fortran flags. 
You need to set both FFLAGS (for F77 stuff) and FCFLAGS (for F90 stuff).

The other problem can probably be solved by setting CPPFLAGS to the correct 
value, which depends on your version of gfortran. You can try -DgFortran, and 
if that doesn't work, -Df2cFortran.

Don't forget to do a make distclean before every attempt.

Thanks,

Ed
