[vtkusers] DEMReader

[Vetria Byrd]

I have converted the sample program TestInteractorStyleTerrain.tcl to C++.
This program uses vtkDEMReader to read in the DEM file.
It compiles with no errors but when I try to run the program I get the following 
error message:

[byrdv](207)% ./testTerrain /hd/byrdv/Data/SainteHelens.dem
 ld.so.1: ./testTerrain: fatal: libthread.so.1: version `SUNW_1.6' not found 
 (required by file ./testTerrain)
 Killed
 
SainteHelenes.dem is the sample DEM file found in $VTK_DATA-ROOT/Data directory.

Has anyone seen this error message before?

Thank you,
Vetria
