Yep, that's certainly better.

Yes, re-reading my own suggestion, you're right. Taking VTK as an example, I
have here
/usr/include/vtk
/usr/lib/vtk-5.0
so yes, it is a bit more complicated. I'll try and think of another solution.

Thanks for the explanation - I'm still trying to learn exactly how you've
managed to generate these wrappers ;-)

I like that solution, let's do that.
