Nevermind, can't use '+'.  I now have in the portfile

compilers.choose        gfortran
compilers.setup         require_fortran

if {![fortran_variant_isset]} {
    default_variants-append +gcc48
}

configure.ldflags-append "-L${prefix}/lib/gcc48 -lgfortran"


I did some digging in the freecad source and found this in 'CMakeLists';

This module can be found in /opt/local/share/cmake-3.0/Modules

Not sure why it doesn't work. 

The c++ compiler is used for linking.
