[arch-general] change user and group in env in PKGBUILD

so i'm trying to update the oracle pkgbuild on AUR. oracle's installer won't run as root, but it thinks that it's running as root. how can I change this? I believe it is supposed to be run as the user and group that it gets installed as what's the best way to add those in the pkgbuild? -- Caleb Cushing http://xenoterracide.blogspot.com
