I haven't used Rudix, but I've had great success using Brew; I switch between 5.1 and 5.2 easily using the process I explain at http://thejacklawson.com/2012/09/switching-package-versions-....

Brew also has Luajit, which I use 99% of the time; it's the environment I run in production because it's so much faster.

I personally prefer brew over other package management systems, especially given that it's open source. Rudix is probably just as good, but I can't see other people fixing packages in a github/issue format like i could with brew.
