/home/cluster/tools/tau-2.22.2/arm_linux/lib/libjogl_drihack.so
    not a dynamic executable

This means what it says. It's one or more of:

• Not a real .so file.
• Not executable.
• Compiled for a different architecture.

Check the output of file libjogl_drihack.so (you need the correct path there).

I'm not an openMPI or Tau user, but I notice there is a Tau package available for armhf Wheezy (or at least, there is for raspbian). However, I doubt this would install into /home/cluster, so evidently you are using something else.

If you compiled the whole thing on the pi, this shouldn't happen either. But if you simply copied the binaries from somewhere else, that's your problem. Do you have a reason for not using the distro package?
