The error message is telling you that you have different versions of
the lamd RPI (not the lamd executable) on your different machines.
So I think you want to check what versions of LAM you have installed
on each machine. If all else fails, you might want to just
uninstall / reinstall LAM on both machines to guarantee that you have
the same versions.
