Didn't try, the script is almost working out-of-the-box, you also need to "sudo make install" for gmp.

FYI, XPM priming (hp8, Ubuntu Server 13.04 64 bit) on Amazon EC2 with High-CPU On-Demand Instances:
- Medium (1.7 GiB of memory, 5 EC2 Compute Units): ~1,1kPPS
- Extra Large (7 GiB of memory, 20 EC2 Compute Units): ~4.5kPPS

I'm trying to tune the parameters a bit to find optimal settings.
