need a help with PortGroup compilers

[Takeshi Enomoto]

Dear Sean,

I am developing a port that relies on makefiles.
I need to set fortran and c++ compilers so I use PortGroup mpi 1.0.
${configure.cxx} has a default value,
but ${configure.f90} is empty.

As far as I read compilers-1.0.tcl ${configure.f90} should be set.

In wgrib2 I manually set ${configure.f90}.

What is wrong?

A part of a pseudo Portfile:

PortGroup           mpi 1.0
use_configure       no
compilers.choose    f90 cxx
compilers.setup     require_fortran
build.env           F90=${configure.f90} \
                    CXX=${configure.cxx}
