Installation error in Arch linux

[JimBee]

I'm getting an error when trying to install gfx.js on Arch linux. The trace it looks like the install doesn't like Arch:

I'm also on Arch. I'm getting a different error, but I'll report it here instead of opening a new issue.

@lendle My workaround for most things that can only work with python2 on Arch is to put this simple script early in my PATH:

#!/bin/bash
# Default to /usr/bin/python unless PYTHON is defined
${PYTHON:-/usr/bin/python} "$@"

Then PYTHON=python2 luarocks install gfx.js.
