Jme physics 2.0 and jme 2.1

Is jmephysics 2.0 compatible with jme2.1 … I seem to have a problem with the TerrainBlock class in a jme physics game it says the cunstructor is not defined … now obviously it is because I have 2 other projects using a TerrainBlock that work fine … the only difference is the physics part … whats going on??

both svn versions (from google.code) should be compatible.

ok thanks … I ended up fixing it.
