Getting a bit further now, but still running into problems. Building with

$ python setup.py config_fc --f77exec=gfortran-mp-4.2
--f90exec=gfortran-mp-4.2 build

results in the error

whereas creating a gfortran symlink and running

$ python setup.py build

results in no error.

Is there a way I can build without creating the gfortran symlink, as I
want to integrate this into a MacPorts Portfile?

Cheers

Adam
