[ncl-install] Unable to install ncl binaries on Mac

[SMITH, JONATHAN WYNN. (GSFC-6133)]

Hello 

I have a macbook 10.5 Intel.  I downloaded ncl_ncarg-5.1.1.MaOS_i386_9.7.0.  It is in my home directory (Users/jonathanwsmith/).  I am unsure of which file I should use to set the environmental variables  in the directory.  .profile is the one I have been using.  It looks like the following:

est -r /sw/bin/init.sh && . /sw/bin/init.sh

##
# Your previous /Users/jonathanwsmith/.profile file was backed up as /Users/jonathanwsmith/.profile.macports-saved_2009-07-27_at_20:29:34
##

# MacPorts Installer addition on 2009-07-27_at_20:29:34: adding an appropriate PATH variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export GADDIR=/Users/jonathanwsmith/grads-1.9b4
export GASCRP=/Users/jonathanwsmith/grads-1.9b4/lib
export NCARG_ROOT=/Users/jonathanwsmith/ncl_ncarg-5.1.1.MacOS_i386_9.7.0/lib/ncarg
export PATH=/Users/jonathanwsmith/ncl_ncarg-5.1.1.MacOS_i386_9.7.0/bin:$PATH

# Finished adapting your PATH environment variable for use with MacPorts.


# MacPorts Installer addition on 2009-07-27_at_20:29:34: adding an appropriate MANPATH variable for use with MacPorts.

I feel the settings above are correct.

When I put in the following command I get an error

jwsmith:~ jonathanwsmith$ ng4ex gsun01n
Resource directory </Users/jonathanwsmith/ncl_ncarg-5.1.1.MacOS_i386_9.7.0/lib/ncarg/lib/ncarg/resfiles> does not exist.

The resfiles are in this directory.

I do not plan to use X11 because I will save the files as .ps or .pdf.  Is X11 absolutley necessary?
 
I am uncertain of what I am doing wrong

I will take any suggestions:
