Usually, the above message means that the compiler either hasn't been
purchased or hasn't been licenced for the system (i.e. there's no way
it'll do anything).

You might try another compiler (which would be a good thing regardless
because /usr/ucb/cc will probably choke on either netCDF or UDUNITS --
it's a very old and non-standard compiler).  To use another compiler, do
the following:

    1.  Go to the top-level source directory.

    2.  Set the variable CC in either the environment or in the file
        CUSTOMIZE, e.g.

            $ CC=/opt/SUNWspro/bin/cc export CC

        or

            % setenv CC /opt/SUNWspro/bin/cc

    3.  Remove the file `config.cache' if it exists.

    4.  Re-execute the configure script.  Trap the output and send it
        to me if something goes wrong.

On our Solaris 2.5 system, the f77 FORTRAN compiler is
/opt/SUNWspro/bin/f77.

A FORTRAN compiler isn't necessary in order to build either package --
you just won't have the FORTRAN interface as a result.  To skip the
FORTRAN portions, just set the variable FC to the empty string before
executing the configure script, e.g.

    $ FC= ./configure >configure.log 2>&1

Please let me know if this helps.
