Ting, I'm not sure what a "Gaussian projected coordinate system" is.. can you elaborate?
To use the VPB driver, you have to specify several additional options so that osgEarth knows how to load the model. Look at the docs here: http://www.osgearth.org/wiki/TileSourcePluginVPB and look at the vpb_earth_bayarea.earth sample. I also suggest you set the environment variable OSGEARTH_NOTIFY_LEVEL=INFO and see if the output gives you any clues.
