[netCDF #MZG-331133]: Missing netcdf.mod

Installing the netCDF Fortran software should install the netcdf.mod file in
the right include directory, assuming you have the necessary permissions to
copy files there.

Maybe you need to set CPPFLAGS or provide an equivalent configure option for
the software you're building to tell it in which include directory to look
for the netcdf.mod file.  My Spotlight says it's installed in several places,
including /opt/local/include/NETCDF.mod installed by MacPorts when I ran 
"port install netcdf-fortran" last summer.  I also see the all lower-case
netcdf.mod file in various other "include/" directories from testing other
versions in the past.

Here are the instructions that work for me out-of-the-box, using CPPFLAGS and 
LDFLAGS environment variables, with either of the current releases of netCDF 
Fortran (version 4.2 or 4.4-beta1), after the netCDF C library is installed:

  http://www.unidata.ucar.edu/netcdf/docs/building_netcdf_fortran.html

I can see from your config.log that the compile line generated to test for
netcdf.mod didn't specify a directory in which to search for that file:

  configure:15807: checking the Fortran 90 module netcdf is available 
  configure:15815: mpif90 -c -g -O2  conftest.f90
  conftest.f90:2.4:

  use netcdf
     1
  Fatal Error: Can't open module file 'netcdf.mod' for reading at (1): No such 
file or  directory

That mpif90 invocation, in your case, should have been something like

 mpif90 -c -g -O2  -I/usr/local/Cellar/netcdf/4.3.1.1/include conftest.f90

so try setting CPPFLAGS=-I/usr/local/Cellar/netcdf/4.3.1.1/include before
running configure.
