Making sure I understand correctly, were you using the distribution on julialang.org/downloads? If you had to do a few things to get it to work, can you file issues? I personally would love to see more such applications and that was the motivation to have an ARM port in the first place.

Also, anything that requires JIT is slow. So having everything pre-compiled if possible is desirable.
