    Hi Jeff,

    I know what's causing the error message, but I'm not sure why because
    you are doing everything right, as far as I can tell. I have an email
    out to a MacOSX UNIX porting group to see if there's an option that I
    need to include when I build the NCL executable.

    I'll keep the group posted about what I learn.
