I think this problem is caused by using the Apple gcc with a different version 
gfortran.
If you got the fortran compiler from a different source, you should use the 
corresponding gcc 
C compiler with it.  For example, if there is a /usr/local/gcc that was 
installed with gfortran,
use that instead of the /usr/bin/gcc from Apple's XCode.  This is not a netCDF 
problem, as
you'll see by Googling for the specific associated error message that appears 
in your
config.log file: 

  configure:5526: gfortran -c -g  conftest.f >&5
  gfortran: error trying to exec 'f951': execvp: No such file or directory
  configure:5533: $? = 1
  configure: failed program was:
  |       program main
  | 
  |       end
