I've loaded your package. A prerequisite is to load OS-Window to make it work.
I've got the DLL call working nicely and the nativeboost with the structure freezing. Now, we should all have a look at: https://github.com/ronsaldo/bullet-pharo and https://github.com/ronsaldo/swig because it looks like the way to go to wrap libraries... Ronie, I know you modified swig for generating Pharo code; Is cloning your swig repo the way to go ?
