This is typically what happens when the emulator is built 
without exporting it's symbols.
Linux build needs a -rdynamic, free-bsd needs, -export-dynamic etc.
The driver is loaded into the emulator and the loader tries to
resolve the symbols it needs from the emulator. 

This should work "out of the box" though ??
