Hi,
I just noticed that new luajittex binaries appeared in the repository
(and while writing this email I got some feedback from Dick).
However there seems to be a tiny glitch, the versions seem to mismatch:
> ./tex/x86_64-darwin/luajittex/luajittex --version
This is LuajitTeX, Version beta-0.78.0-2014010308 (TeX Live 2013/dev)
> cat tex/x86_64-darwin/VERSIONS | grep jit
luajittex: beta-0.78.1
