`mix lfe.setup` fails.

It seems mix_lfe doesn't work with the latest version of either Elixir or LFE. I have installed the

I believe I have isolated the error to be in LFE: https://github.com/lfe/lfe/issues/489

[meddle0x53]

Hmm yeah, I also tried to upgrade it (haven't used that tool for years) and it seems I can not even depend on lfe in mix right now... Saw your issue in their repo, no answer, tried some things myself but to be honest it is related to how mix uses rebar to compile erlang deps. Basically as part of the LFE dep compilation it does this:

And this is the error, which I spent some time debugging, but am not sure if I can understand even...
