I've checked it in:

I'm in the middle of debugging a ton of corner areas so you'll have to
excuse all the "printf" style debugging lines. Pretend it's a very messy
construction site. :-)
See the README for setup directions. Then you can try the
'small-pyramid' demo:
$ ikarus --r6rs-script ~/scheme/box2d-lite/demos/small-pyramid.sps
On my system, the "full" pyramid based on the one that comes with Box2D
Lite runs pretty slowly. But the 'small-pyramid' demo has good
performance.
By the way, the original Box2D Lite C++ source code is at:
http://www.gphysics.com/files/Box2D_Lite.zip
That'll come in handy if you want to help me debug the Scheme
version. :-)
