Hm.. but each person knows best the environment they work for.  It would be
presumptuous of me to tell him pybindgen is the better choice.

I don't have the full benchmarking setup, but here's how to wrap that
example (attached).  I had to add a default Vec3 constructor, since
pybindgen does not like very much classes without default constructors.

You generate the module with:

   python vec3-gen.py  > vec3module.cc

Compile with something like:

   g++ -O2 -fPIC -shared -I /usr/include/python2.6 vec3module.cc vec3.cpp -o
vec3.so

As for the benchmarking stuff, I leave to the original poster.
