Thanks Mike, this is fantastic. I have used the Debian packaging to
produce .debs of the current HEAD for the Raspbian flavour of armhf.
These are uploaded to http://archive.raspberrypi.org (which is in the
default sources.list for anyone using the Raspbian image we have at
raspberrypi.org/downloads). So, if anyone wants to give it a go `sudo
apt-get update && sudo apt-get install luajit`.
My repo is https://github.com/asb/luajit2-debian in case anyone wants
to double check any of the packaging.
Here's a sample scimark.lua run on the Raspberry Pi at stock
frequencies (ARM1176 700Mhz):
$ luajit scimark.lua
