Hi Martin,

I'm moving this response over to the support list since a lot of users
will probably want to see it.

We're becoming more serious about NetCDF and have added it to the
following verification experiments:

  aim.5l_cs, dic_example, exp0, global_ocean.90x40x15, 
  hs94.cs-32x32x5

So to get them all to pass you will need to first install NetCDF.  Its
really easy.  The commands for the Mac with g77 are:

  $  wget ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.5.1.tar.Z
  $  gunzip netcdf-3.5.1.tar.Z
  $  tar -xvf netcdf-3.5.1.tar 
  $  cd netcdf-3.5.1/src/
  $  export CFLAGS="-Df2cFortran -fPIC"
  $  export CPPFLAGS="-DNDEBUG -Df2cFortran -fPIC"
  $  ./configure --prefix=/usr
  $  make
  $  sudo make install

and this was verified yesterday on a brand-new dual-G5.

For Linux systems using g77 as the compiler, you can do the same
source-based install as above or you can use convenient binary RPMs
available at:

  http://mitgcm.org/eh3/packages/

which have been tested on RH 8 and 9, Fedora Core 1 and 2, and SuSE
9.x.  I've become the official packager of NetCDF for Fedora Extras and
it will soon appear in the list of available packages at:

  http://www.fedora.us/

For non-g77 installs, you may have to use a slightly different set of
compiler flags.  I've installed NetCDF for the following compilers:

  Intel ifc v5.x, v6.x, 7.x;  Intel ifort v8.0;  Intel efc
  PGI v3.2

and the NetCDF home pages have plenty of details on how to get it
working on other systems:

If you run into any problems, please let us know and we'll try to help.

Ed
