Yes, the auto-geometry stuff is only available as part of Chipmunk Pro.
The core parts for the geometry extraction and simplification is in C so it can be bound to pretty much anything. However the part that makes the deformable terrain really efficient, the tile cache, is written in Objective-C currently as it performs a lot of memory management. Chipmunk Pro does come with full source though.
