what do you think "a regular user" of ubuntu/suse/fedora/arch/etc. looks like?
back when I was using arch I wrote pkgbuilds instead of configure/make/installing to my home folder. kept my ./local/(bin|lib|share) clean and meant I could update it easier or uninstall it with pacman.
As to runnning random build scripts, well I already do that anyway. Any software that isn't provided by my package manager requires me to run random build scripts from random people. I sure as hell am not reading through every line of code in say... trealla prolog before make-ing it.
