[ncl-install] Display Error NCL Install

[Dave Allured - NOAA Affiliate]

Noa Margalit,

These messages indicate that your DISPLAY environment variable is not set
correctly.  Please see the DISPLAY instructions in the NCL install
documentation:

    http://www.ncl.ucar.edu/Download/install.shtml#SetDISPLAY

As noted, you may need help from your system administrator or software
consultant to get the correct value and method for setting this variable.

FYI, on my Mac, this variable is automatically set for me on login.  The
setting includes a unique session key which I think changes each time I log
in.  Therefore my setting will probably not work on your Mac.  However I
include it here, in case it might give you a clue.

mac56:~ 1> env | grep DISPLAY
DISPLAY=/private/tmp/com.apple.launchd.SvKYd9sPHT/org.macosforge.xquartz:0

--Dave
