Strange, hugin works fairly well on the other intel machines, and nona
doesn't use any gui at all, its a pure console mode application. I think it
might be related to the UB build.

Ippei, if you make a new snapshot to test the UB build, can you use the
current CVS? Probably it hasn't been tested on OSX since 0.5, and should fix
the optimizer crash some people have experienced on OSX. I'd like to release
hugin 0.6 after adding some more output projections to hugin.
