[ncl-install] running ncl on cray machine using aprun

[Jatin Kala]

Hi Mary,
Just FYI, we have found a solution to this problem.
Compiling from source was not necessary. Turns out that to run ncl on 
Cray machines, you need the following:

|export NCARG_USRRESFILE=$NCARG_ROOT/hluresfile
export MY_TMP=/scratch/y98/julia/tmp
TMPDIR=$MY_TMP aprun -n 1 $NCARG_ROOT/bin/ncl script.ncl|

Not explicitly defining NCAR_USRRESFILE caused the seg fault.
We got this info from another group which runs ncl on a Cray machine:
http://www.archer.ac.uk/about-archer/software/modcatalogue/ncl/

This did the trick for us. Might be worth putting this link on NCL 
install web-page if anyone else is running ncl on Cray machines via aprun.

Cheers,
Jatin
