Actually, if you're building in a chroot environment (which I do with aurutils --chroot), git is not installed by default. So I agree with lilmike that git is in fact a build requirement. This PKGBUILD fails inside a buildchroot (which is Arch base + base-devel).

No, no it shouldn't. Having git installed is a base requirement for using AUR.

This package should makedepend on git so it can successfully build in a chroot.

Error: git program not found. Make sure Git is installed and is available in your PATH (or you may want to edit the variables.GIT value in file /etc/luarocks/config-5.1.lua)

Please do not mark this as out of date, it's the latest version that works with Lua 5.1 (some programs still haven't converted to Lua 5.2)
