Hi Arnaldo,
Thanks for reporting this, Tzvetomir is going to take a look at the
warnings happening in the traceevent directory.

You may want to install the user-basic-dev bundle.

Also present in user-basic-dev.

Ditto.

This one is in desktop-dev. We don't have that enabled in our own build of
perf, though.

user-basic-dev too. We're almost rid of Python 2, do you need it?

Assuming xz is sufficient for this, user-basic-dev.

Nope, patches to make perf build with python3 (while still building with
python2, if that is what is available) were already merged, IIRC.
