Torsten,
I can share with you my experience. It is a hack, though.
When I set up distributed computation on multiple machines
using Remote.manager,
(since I could not change the system-wise stuff),
I did the following hack.
in mozart_home_path/mozart-1.3.2/share/lib/dp/
I modified the line
case {OS.getEnv 'OZENGINE'} of false then 'a_path_to/ozengine'
the orignal line was
case {OS.getEnv 'OZENGINE'} of false then 'ozengine'
--------------------------------------------------------
I do not know if you are using Remote.manager,
but the environment variable OZENGINE may be relevant.
