[ptx] optimization and amd64

[Mickael Profeta]

Hi

I discover Hugin to create my panomara and I quickly found it wonderful.

I compiled it on debian sid on an amd64 machine, and it seems to work 
quite well (at least hugin + nona + enblend)

Yet I discover recently that I have a trouble with PToptimizer: it 
segfault when you ask him to do some distortion optimisation.

Is this problem known? Or is there another alternative to PToptimizer to 
perform those optimisations?

If you need some more informations I will be please to send them quickly.

Thanks for any help

Mike
