HI ? Could you sign your emails with the name you'd like to addressed with, thanks.
As for the error, this points to the OSG failing to create a grpahics context on your system. What hardware and drivers are you using? In recent versions of OSG/VPB it's possible to run VPB builds without using a graphics context. For this you'll need to compile the OSG against the NVidiaTextureTools SDK so that the nvtt plugin is built.
