no, I got it working!
I was right the 1st time about the ode flag - I just hadn't
completely removed all the scons tmp files.
I will commit the fix - just simply requires the -DdSINGLE flag to be
passed during compile time in the SConfig

no, scratch that - this would require major changes to fluxus,
changing basically every datatype to double from float.
not sure how to fix this, except to create a variant using single-
precision maths on OS X. otherwise, any attempt to use libode will
result in garbage numbers being passed in.
what do you guys think?

no, I see - by default, libode is double-precision on OS X. you
can't just use the compiler flag to switch it to use single-
precision.
this is actually a pain, but fixable - all bounding boxes and
physics functions will need to use doubles instead of floats. I
started doing this, but I'm not exactly sure of all implications,
because the physics bounding box relies on the Primitive-
>GetBoundingBox() function.
I might try it out and see...

I'm working on a fix, think it's just a matter of adding compiler
flag -dSINGLE
let you know in a sec if it works

I can't reproduce this with ode 0.11.1 - is there a particular
command
which crashes? I've ran self-test, collide-seq.scm and
physics-joints.scm ok.
on osx i tried ode 0.11.1 with this script:
(define b (build-cube))
(active-box b)
got the following crash:
