Physics engines

[Ingemar]

Strange, because Chipmunk(about which you wrote in first post) exists on every platform - Windows, Linux, MacOS X and some time ago I compiled it for iOS, so it can be used with FPC via static linking...

Yes, and that is my primary choice as I mentioned, and I have the static library on my disc already. But if someone had some FPC demos ready, it would be unnecessary to port the C ones. Or pointer to other alternatives which don't require major rewrites.

But Chipmunk isn't generally what I see people recommend for ragdoll physics. They recommend Box2D, and there is also the Pappe library which promises support for ragdoll physics, but both these seem awkward to port to me.

I am not afraid of porting code, far from it, but my time is limited and I must choose my battles. Small demos are easy to port, big ones are harder, and entire frameworks might take lots of time. Sometimes you just have to step back and see if there are other paths than the one you had in mind, before going too far on that one.
