Troubles on Ubuntu 11.10 although setting the environmental variables

Hello everybody!
My name is Jenny and I'm from Italy!!
I have some troubles with the installation of the NCARG Graphics :(!

My computer is running under Ubuntu 11.10.
To find out what version was correct for me I've typed:

>uname -m
>i686

and

>gcc --version
>gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1

I've downloaded this version (no OPeNDAP)

ncl_ncarg-6.0.0.Linux_Debian_i686_gcc445.tar.gz

I've installed on my notebook:
- the NCL software (that seems to be installed correctly!)
- the X packages for Ubuntu ("xorg-dev" that includes also the libraries
"libx11-dev")
- the csh shell (I'm under bash but I've installed anyway)
- the gfortran95 package

I've set the environmental variables in my .bashrc file:

>export NCARG_ROOT=/usr/local/bin
>export PATH=/usr/local/bin:$PATH
>export LD_LIBRARY_PATH=/usr/lib

after I typed

>which ncl
>/usr/local/bin/ncl

in the terminal!

When I write:

> sudo ng4ex gsun01n

the result is:

>Path to directory(root) not found [ environment variable not set ]

Did I do something wrong?
Sure! But I don't understand where :(

I really need the help of you experts!
A big thank you in advance ^___________^!
