Pierre, I figured out the problem. The problem was exactly what you said. I didn't need the Vrjuggler libraries since I already had the python bindings from the ggt code. What happened was that in building the python bindings, the release version of python boost was used and I was compiling my code in debug mode using the debug version of python boost. I linked my code againts the release version of python boost and it worked as expected.
