Trouble building with Elixir 1.1.1

[jordan0day]

I'm having trouble using hash-ring-ex with an Elixir 1.1 project -- obviously the mixfile specifies 1.0.0, so I tried playing around with it, but just upping the elixir version requirements didn't seem to do the trick. The project will compile, but it looks like the hash_ring_drv.so isn't being copied to the priv/ folder?

Since 1.1.0, it looks like Mix has been able to compile rebar projects -- I'm not sure if that's causing the issue here?
