[ncl-install] HDF

Hi Dimitra,

It appears that your HDF build is succeeding in creating the  
necessary libraries but failing when trying to build associated  
tools, in particular
the tool 'ncgen.'   Please note that 'ncgen' as provided by the HDF  
distribution is not necessary to build NCAR Graphics and NCL.

It has been my experience in building HDF on a fairly wide variety of  
platforms that sometimes the libraries build correctly, and the tools
do not.  I do not worry about the tools, because as noted they're not  
necessary, and I move on.  As well, the netCDF distribution provides the
same subset of tools (ncgen, ncdump).

My suggestion would be to verify the libraries are indeed  built, and  
proceed with the rest of the process to build NCAR Graphics.

Please note: the NCL team does not support the HDF source code, nor  
the building of it in its entirety.  If you are uncomfortable with the
notion of an incomplete overall build of HDF, please contact their  
support staff for further assistance.
