[ncl-install] newbie install problem

[Benjamin Laken]

I am having a problem getting NCL to run, I have installed CYGWIN, and 
NCL, and I have changed my .basch file to have the lines included:*

export NCARG_ROOT=/usr/local
export PATH=/usr/local/bin:$PATH

export DISPLAY=:0.0

*(Although I dont have a  .cshrc file in my home directory so i have not 
added the lines *

 setenv NCARG_ROOT /usr/local
 setenv PATH /usr/local/bin:$PATH

 setenv NCARG_ROOT /usr/local
 set path=($path $NCARG_ROOT/bin) )


*when I attempt to generate the NCL test using... *

cp $NCARG_ROOT/lib/ncarg/nclex/xyplot/xy04n.ncl .
ncl xy04n.ncl

*I get the following response ...*

NCARG_ROOT: Undefined variable

futhremore when i type 'ncl' in to my x window it loads up with the 
following errors -*

warning:Unable to Get System Resource File Name?

fatal:GetSysAppDir:Unable to get a default value for the system App

*Any ideas how I can fix this and get NCL up and running?

Thanks in advance,
