libode is installed in /usr/local/lib on my system. I've attached a modified 
setup.py which searches for libode.

I still got compilation errors though until I removed the generated ode_*.c 
source files and had pyrex re-generate them. Then it all worked fine with one 
test failure that looks like a rounding error:

All the examples (except the one requiring cgtypes) work fine.
