So I was trying another system here as a sanity test (as my main dev box 
is not working either). And this other system is debian and only 
supports python up to 3.5, so that is why I have 
/usr/local/bin/python3.6 as an alt, i.e. I downloaded and built myself.

Anyway, I do have python3-dev:

john@debian:~/linux/tools/perf$ sudo apt-get install python3-dev

python3-dev is already the newest version (3.5.3-1).
