Its a modifier to --download-hdf5 - i.e it enables fortran-bindings in the hdf5 build.

Yes.

Its not a separate download of fortran bindings [but modifier to --download-hdf5]

Here is what you would do:

$ ./configure --download-hdf5=1 --download-hdf5-fortran-bindings=1 --with-packages-download-dir=$HOME/tmp
