[ncl-install] running ncl on a compute node of a cluster

[Mary Haley]

Po-Lun,

You can't turn this feature on and off, unfortunately. The NCL  
software has several dependencies on the X11 libraries, and I'm  
guessing in your case, it's looking for X11 shared libraries and can't  
find them.

The error message should hopefully tell you what kind of libraries  
it's looking for, and you should be able to copy them over from  
another similar machine.
