[ncl-install] Display Error NCL Install

[Noa Margalit]

Hi,
I keep getting the same error copied below no matter what I've tried. I
tried writing it to a pdf or a ps file instead of X11 but get the same
display error. I set the display value to the ip address of the remote
machine and am working on a mac where I have installed "XQuartz 2.7.11". I
also logged out and logged back in trying both ssh -X and ssh -Y and
neither work. The files are being created in my working directory but are
not opening a file to display the output. I have successfully compiled both
wrf.exe and ideal.exe.
Thanks,
Noa Margalit
