The above message contained the following:

It appears from the above that the compiler that was used to create the
binary netCDF distribution defines the global symbol "_IO_stderr_" and
that this symbol is not defined by your runtime environment.

I suggest that you try rebuilding and reinstalling the netCDF package
from source. This should ensure compatibility. Please try the following:

    1.  Go to the top-level netCDF source directory.

    2.  Perform steps 3 through 5 described near the end of the file
    INSTALL.html.

    3.  Ensure that the environment variable CPPFLAGS contains the
    string "-Df2cFortran" (I'm assuming that you use the GNU C
    compiler).  For example:

        export CPPFLAGS="-Df2cFortran"

    or

        setenv CPPFLAGS "-Df2cFortran"

    This is the step you were missing.

    4.  Perform steps 6 through 9 described near the end of the file
    INSTALL.html.

Please let me know if this helps.
