[ncl-install] FINALLY WORKS ....thanks to all for the educatioin

Hi Joseph,
I'm glad to hear you were able to work through your problems. I did want to comment about the 'mystery' of the Apple file systems. It is true that unlike other Unix systems, the Apple OS X file system is  (by default anyway) case insensitive. However, as you have noticed, files and directories do have a preferred spelling that recognizes the case. It is the spelling that they were first created with. So although you can refer to the 'Applications' directory as 'applications' its "real" name is 'Applications'.  It takes a little while to get used to especially if you are importing directory trees from other Unix file systems. A gotcha that we experienced when first working with OS X was that we had a few places where there were files in the same directory that differed only in their case. That can totally screw things up.

I have set the default sign on shell for my IMac to tcsh and the .cshrc file seems to be invoked because it uses the alias for ls to be "ls -CF" which it did not do before when the sign on default was bash. I tried creating a .tcshrc file but that does not work.  Also, I have tried from the bash shell just setting to csh and also no go.
