[ncl-install] Mysterious missing symbol error in NCL libraries

[Mary Haley]

Hi Richard,

The likely issue is that the GKS library didn't get fully built, and the
culprit is probably the "cdrivers" directory under the
"$NCARG/ncarg2d/src/libncarg_gks" directory.  There's some source code in
that directory that depends on cairo, which is an external package required
by NCL V6.3.0. It wasn't required by NCL V6.0.0. My guess is that the build
failed because it couldn't find some required include files by cairo and/or
freetype.

Can you email me the full build log so I can see where the error is?
