[ncl-install] Problem unzipping/untarring NCL setup file

[David Book]

I use Firefox as my browser and I'm running under Windows 7 on a 64-bit 
computer. I downloaded and successfully started Cygwin/X.  Using Windows 
Explorer I can see my home directory, C:\cygwin\home\book. I can open a 
Cygwin/X window by clicking on my Cygwin desktop icon. 

(But when I open a Cygwin/X window, the prompt reads
Book at Book-Enigmatics  instead of
Book.  I don't understand this, but I don't think that's the source of my 
problem.)

Then I downloaded
/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar.gz  and saved it in my home 
directory. I can see it there, either by opening the directory with Windows 
Explorer
or by opening a Cygwin/X window and doing 
ls -a.  Then I tried to install it, following the instructions under 
"Install NCL" in the chapter entitled "Installing Cygwin/X (Windows)" in 
the NCL online manual. I typed 
cd /usr/local .  No problem. The prompt says that I am now at 
/usr/local ,  as it should. But when I type
gunzip /ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar.gz ,  I get this 
message:  gzip: 
/cygwin/home/Book/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar.gz: No such 
file or directory  I tried downloading the file again again. No luck. Then 
I downloaded the unzipped file,
/ncl_ncarg-6.1.0.CYGWIN_NT-6.1-WOW64_i686.tar , and tried untarring it 
(i.e., skipping the gzip step). No luck. My system still says it can't find 
the file and/or directory. 

Can someone tell me what is going on and how to fix it?
