The solution I imagine is the following: PolyBoRi has a boost::python
interface, but we do not install it since we do not use it. It could
easily be added back. That way we do not have two boost installations
fighting for supremacy. Since PolyBoRi is in Sage and considered very
important Cuda breaking PolyBoRi via its boost requirement is a big no
no and will not happen. But the way suggested above will make both
camps happy. This might happen in the next week, i.e. we would likely
have an optional PyCuda.spkg by Dev1 at SFU.

Yeah, and many times one needs to use boost CVS in order to work
around bugs in less common OSes like some BSD flavors. So depending on
the system provided boost install is something I would prefer to
avoid.
Re cwitty: I do not mind if you redid the boost::python code in
Cython, I am just saying that I do not have the time to do it myself.
But I would be more than happy if you did it :)
