Panda Bullet

I tried to compile a c++ panda program wishing to use bullet.

I get

1>C:\Panda3D-1.8.0\include\bullet_includes.h(20): catastrophic error: cannot open source file "btBulletDynamicsCommon.h"
1>  #include "btBulletDynamicsCommon.h"

So what are the bullet include files needed for use in a c++ panda app, and where are they located. Grazie.

Another concern: I tried to compile a complete Panda3D version including the latest Bullet svn (2.8?) (from bullet svn repository).
Here is what I get.
