The last few weeks I've spent some night hacking time to get Erjang to be able to run Elixir. Here's a short note on the current status for those interested.
The bottom line is that we can now boot the Elixir REPL, it looks like this:
krab$ ./bin/iex
Warning: could not run smart terminal, falling back to dumb one
