Native CAM - How To Install?

www.linuxcnc.org/testing-stretch-rtpreempt/

I suggest booting in LiveCD mode and running the latency test first, it may be that preempt-rt isn't good enough on your hardware.

Latency was something around 4900 running couple of movie files and surfing on wheezy.
I will try that stretch next.

Holly cow latency has jumped to 3903790 on 25us base thread. It seems thats a no go too.

This is getting more difficult than I expected, last machine run three years without missing a beat. And was not even that hard to get working. How come everything is so difficult now?

LinuxCNC depends on RTAI for good realtime performance, and RTAI development has lagged badly.

Can someone help with the curl problem, my linux skills are depleted, so step by step for 10 iq people kind of solution needed.
I installed curl from some swedish link I found but still Ncam wont install.
tried on another computer clean install and same deal my time is going on this as I should be making everything else. what am I missing?
Used to love linuxcnc but now I dont like it one bit anymore fourth day going by with this.

Unable to run:
curl packagecloud.io/install/repositories/Fer...wheezy&source=script

This is getting down right ridiculous needed manually run ldconfig to get the curl working, another evening gone finding that out by reading countless posts. Still cant see nativecam anywhere no matter what I type in terminal thats on any instructions. How can this be so hard after couple of years?

Should it go like this or what is next to do? What am I doing wrong?
