Thanks. Based on AM's response I took another look at the PAR docs and found out about PAR_GLOBAL_TEMP. But I'm confused about whether that var needs to be set on the target machines or if I can just set it on the build machine. If I could set PAR_GLOBAL_TEMP to something like ~/tmp/par/program_name on the build machine and it would just work on the target machines that would be the best situation.
I'll experiment with this when I get to work.
