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

[Mary Haley]

Hi Jatin,

Glad you figured it out. Sorry we didn't respond sooner, but I've been out
of the office, and I'm not sure anybody else knew the answer.

I've filed a bug report on this (NCL-2256).  It sounds like it's simply
failing because it's trying to look in a home directory, which doesn't
exist.
