[ODE] mising symbols

[Wesley Smith]

Well, I may have spoken too soon.  I get these linker errors after compilation:

ld: Undefined symbols:
__ZN5dxRayC1EP7dxSpacef
__ZN7dxPlaneC1EP7dxSpaceffff
__ZN6dxGeom8AABBTestEPS_Pd
__Z15dCollideSpheresPddS_dP12dContactGeom

heightfield.o reference to undefined __ZN5dxRayC1EP7dxSpacef
heightfield.o reference to undefined __ZN7dxPlaneC1EP7dxSpaceffff
plane.o reference to undefined __ZN6dxGeom8AABBTestEPS_Pd
ray.o reference to undefined __ZN6dxGeom8AABBTestEPS_Pd
sphere.o reference to undefined __Z15dCollideSpheresPddS_dP12dContactGeom
sphere.o reference to undefined __ZN6dxGeom8AABBTestEPS_Pd

Does anyone know where they might be found?  I can't seem to sniff out
their origin.

thanks,
wes
