On 13.04 64bit you will run into an issue of PA not being able to find "libudev.so.0" Ubuntu 13.04 is using libudev.so.1 so we just need to make a symbolic link for it. Took a bit of digging but I found where Ubuntu has it: Code: cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.1 libudev.so.0 You will also find it complains about cannot find "libTelemetryX64c.so" though the game will run without this (so I am not sure if this is 100% needed or not).
