This probably happened because one node has usysv support and the other
doesn't. You can run "laminfo" on both machines to get a list of
supported modules. If usysv doesn't appear on the Mac list, then
you'll either have to use a module that is available on both machines
or rebuild LAM for the Mac.
Note that there is a bug in the USYSV rpi for G5 hardware. If you are
running on a G5, you should either avoid the USYSV rpi or upgrade to
LAM 7.1.2b22.
Hope this helps,
Brian
