[ncl-install] mac installation issue

[Mary Haley]

Dear Crystal,

I believe you have done everything correctly with the environment variables.

The problem you are running into has to do with UNIX file permissions.  When you run "ng4ex", it tries to copy an NCL script into the directory where you currently are, and then run it.

There are some directories that you are not allowed to write files to unless you are a "super user" or have special administrative purposes, and my guess is that you tried to run "ng4ex" from one of these directories.

Try running the command from your home directory instead:

  cd
  ng4ex gsun01n -clean

The "cd" command without any arguments should cd to your home directory by default.
