I just got a ping from this issue, and it looks like I didn't see it when it first came up. It's been long enough, that perhaps you no longer need this answer, but here it is anyway. These linker errors are due to missing the Intel OMP library, libiomp5.so. Someone else had similar issues recently on our forums, and I gave them a response here. Give that a try, and let me know if that doesn't fix the issue.
