With the patch, math/octave fails for me on 9.2-RELEASE/amd64 and
10.0-BETA4/amd64 with:

checking for amd64-portbld-freebsd(9.2|10.0)-gfortran... f77
checking whether we are using the GNU Fortran 77 compiler... no
checking whether f77 accepts -g... no
checking how to get verbose linking output from f77... configure:
WARNING: compilation failed

checking for Fortran 77 libraries of f77...
checking for dummy main to link with Fortran 77 libraries... none
checking for Fortran 77 name-mangling scheme... configure: error: in
configure: error: cannot compile a simple Fortran program

Full logs attached (each with and without your patch).

In both cases, it tries to use f77, while the original port uses gfortran46.

Any idea what is wrong on my system?
