This is caused by trying to link with a netCDF library built on an old
RedHat 8 system.

To get around this problem, you will either have to recompile and
install the library from source, following the installation
instructions on our web site:

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

or try installing a later binary distribution, such as the version
3.6.0 netCDF library available in:

  ftp://ftp.unidata.ucar.edu/pub/binary/linux_2.4-i686/

or use one of the RPMs for netcdf accessible by using "netcdf rpm
3.6.0" as Google search terms.
