rpiece on macosX

here is pillo with another beginner question....

i m tiyng to use rpiece on osx + linux

i made it work on linux dual proc system (a rocket) , on two mac computers (some problems, overlapping calculations, little performance gain)

the problem:
nfs sharing between mac and linux, the linux box mount a mac folder with a scene.
launching rpiece on the mac, solved
launching rpiece on linux

now the problem: due to network lock manager, the linux system can't read sync file (i m the same user on both systems) and stops.

any idea?

the mac doesn't seem to have any network file locking trick running... may be the name is not the same as on the linux system...

what can i do?
