Adafruit Feather nrF52 build error: adafruit-nrfutil not found on ubuntu 18.04

[neu-rah]

#26

Have same problem on linux (ubuntu 18.04), on the script it seems that other OS rely on the tool being on path...

from this PR: #27

on ~/.platformio/platforms/nordicnrf52/builder/main.py

nrfutil_path = join(FRAMEWORK_DIR, "tools", "adafruit-nrfutil", os_platform, "adafruit-nrfutil")

would serve both systems "macos" and "linux2"

os_platform="linux2"
created linux2 folder on ~.platformio/packages/framework-arduinoadafruitnrf52/tools/adafruit-nrfutil

linked adafruit-nrfutil to ~/.local/bin/adafruit-nrfutil

ln ~/.local/bin/adafruit-nrfutil

that is the correct path on my system when following install procedures from https://github.com/adafruit/Adafruit_nRF52_nrfutil
pip3 install --user adafruit-nrfutil

I could patch this (not sure if it worth, because it can vary from system to system?), anyway the linux2 folder would be missing along with the link, and i have no idea where in the toolchain install process this can be done... at least the main.py could check file existing before path rely?

I think clearer instructions in the Linux section at https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/arduino-bsp-setup would suffice here, particularly the line about "Add pip3 installation dir to your PATH if it is not added already. Make sure adafruit-nrfutil can be executed in terminal by running..."
For the neophyte, going from "Add pip3 installation dir to your PATH" to the real work required - for example, in Ubuntu 18.04.3 I edited my ~/.profile file and added:

# add pip3 site packages folder to PATH for adafruit-nrfutil PATH="$PATH:$HOME/.local/bin"

Which did the trick. Posting for posterity.
