The problem is that applications have to allow for the 64-bit interface and many have not been designed for that. I still want to convert GEMMA and it is a pain.

That is the way forward. Convert packages one by one and see if things break. I would not trust numpy/scipy at this point to handle 64-bit correctly unless they explicitly converted. Pj.
