[ncl-install] NCAR Graphics test doesn't work

[Orion Poplawski]

FYI - you would need to install libXext-devel as well.

My actual need for ncarg is small to nonexistent, but I thought since I was playing around with it, I thought I'd try to see why it didn't work.  I guess that also explains a lot about the Fedora ncl package as well--doesn't work there, either ;-).
