[netCDF #JSU-487825]: unable to locate netcdf.mod

Oops, sorry, I did miss that.  Now I see your fink installation was installing 
the latest netcdf-4.2.1.1 C library and an older netcdf-3.6.3 combined C 
library 
and Fortran library.  What I would recommend is installing the 4.2.1.1 C 
library,
as you have done, then compiling the netCDF Fortran library version 4.2 from
the source tarball, telling it where you installed the C library, as described 
here:

  http://www.unidata.ucar.edu/netcdf/docs/netcdf-fortran-install.html

You'll see from the above that it makes a difference whether the netCDF C 
library
is installed as a shared library (recommended) or as a static library (will
require more library flags to compile netCDF applications).

It would be good to uninstall whatever fink installed for the netcdf-3.6.3 
version,
as we haven't tested the combination you have installed.

Yes, /usr/bin/gcc is the Apple C compiler, which apparently is incompatible
with some versions of gfortran.  Also gcc compiles 64-bit objects as a default
whereas some versions of gfortran build 32-bit objects unless you explicitly
include the -m64 flag or use the "-arch x86_64".  NetCDF works fine using a
32-bit model, so you could try -m32 with gcc and the default with gfortran.

Also with some versions of XTools on MacOS-X, we need to set the environment 
variable

  lt_cv_ld_force_load=no

before running configure, though I don't know if that's necessary with the 
latest 
tools ...

If any of the above suggestions work, please let us know.> On Mon, 24 Sep 2012,
