Hi Shayne, I don't know what might be causing problems on your system, debugging this type of thing remotely is next to impossible.
The best I can do is suggest trying the svn/trunk version of the OSG & VPB. With VPB is now possible build using NVidia texture tools and with this avoid the need for graphics context and associated graphics card - instead you can just compile and run with Mesa libs. For more info have a look at the recent threads on osg-users and osg-submissions about NVidia Texture Tools integration. Robert.
