Re: Re: need help linking

All,

Jason and I are looking into this one offline.

Interestingly, a shared library is being used for the NCAR Graphics
"ngmath" library, and this is not something that our build is set up
to do automatically. I'm checking to see if there is something
wrong with the way it was done here.
