I edited out that because the grep found pi in the wrong place...

I solved my root/pi problem back in Oct 2015.
You can read about it here:
http://lists.lazarus.freepascal.org/pipermail/lazarus/2015-October/094438.html

Specifically see how the change from using /dev/mem to /dev/gpiomem
made it possible to run as user pi.

I personally totally detest having to be root in a development system
and having my programs require root to run.
I don't have to anymore.
