In netCDF 3.5.0, the Fortran 90 interface doesn't work on platforms
like the Cray T3E, for which the default integer size is 8 bytes.  You
can use the Fortran 77 interface (as well as the C and C++
interfaces), but you need to specify that the Fortran90 interface will not
be built.  You do this by explicitly setting the F90 environment
variable to an empty string (F90='') before running the "configure"
script.  Then delete the "config.cache" file and rerun the configure
script, as in the installation notes:

  http://www.unidata.ucar.edu/packages/netcdf/INSTALL.html#unicos

If that doesn't work, please try netCDF 3.5.1-beta (still specifying
F90='') from

  ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.5.1-beta.tar.Z

Unfortunately, we don't have access to a Cray T3E here to test with,
but several sites have managed to successfully compile and install
netCDF 3.5 on Cray T3Es, so you might also ask them what environment
variable settings succeeded for them, for example:

  http://hpcf.nersc.gov/software/libs/io/netcdf/
  http://www.awi-bremerhaven.de/EDV/netcdf.extern.html
