  Hmm. Well, you're going to experience some grief being on such an old release. There are
many bugs that have been fixed since 1.2, I'm sure. You will probably encounter them.
Depending on your schedule, you might strongly consider trying to compile your codebase
against a current OpenSceneGraph-2.8.2 release. We're going to be hard-pressed to help you
with issues on such an old codebase. And, you're going to have to update at SOME point.

  Ok.

  Well, I have no idea how your co-worker was using OSGDem. Is it anyone we'd know?

  Are you trying to compile an OSGDEM/VPB release from a modern VPB code checkout, or what
version of the VPB code are you using? Your code ingredients here may be toxically immiscible.
