I'll re-word the documentation noting that using '--disable-netcdf'  
is the appropriate thing to do.

Please edit the files

	NclHDF.c
and
	NclHDFEOS.c

located in the directory .../ni/src/ncl directory (relative to your  
source code install root point) and remove the following line from each:

	#include <hdf/netcdf.h>

There's no longer a need to include this file, and with newer  
releases of HDF4, the NCL-recommended installation of HDF4 will not
install this file.  This is 'fixed' in the next release of NCL, and  
now documented in the web documentation discussing NCL installation.

My apologies for the difficulties.
