You should not need to specify any configure options (other than -- 
prefix) to get netcdf support. I did not write any code to support the  
"--with-netcdf-include" option...

What you're trying to build here is a utility called 'udunits' -- that  
is something that is built along with the library, but it is not  
necessary for GrADS.

Look for a file called libudunits.a  -- that is what GrADS needs --  
and put it in your $SUPPLIBS/lib location.
