physics-27 fails to start

[quozl]

physics-27 bundle installs fine but does not start, activity log contains:

My tests have been with 32-bit and 64-bit i386 systems.

Dumping dir(box2d) immediately after import shows b2QueryCallback is missing.

The lib/box2d_32, lib/box2d_64 and lib/box2d_arm7 directories have been generated by different versions of swig.

I'm not sure how to debug this further.
