The first setup.py command is supposed to select the fortran compiler. But I cannot get it to recognize the gcc44 fortran compiler. This is my attempt after fixing the portfile:

build {
    system "cd ${worksrcpath}; ${python.bin} ${worksrcpath}/setup.py config_fc --fcompiler=gfortran-mp-4.4 --noarch build"
    system "cd ${worksrcpath}; ${python.bin} ${worksrcpath}/setup.py install --skip-build"
}

it returns this error:

If i manually create a simlink from "/opt/local/bin/gfortran-mp-4.4" (the gcc44 fortran compiler) to "/opt/local/bin/gfortran" then i can get it to work if change the first setup.py command to:

system "cd ${worksrcpath}; ${python.bin} ${worksrcpath}/setup.py config_fc --fcompiler=gfortran --noarch build"

But I don't know how to get the portfile to work without that simlink.
