Compilation error in file lib/blockchain/contract.ex

Hi!

I tried to run this, but I'm getting:

user@ubuntu:~/sources/elixir_tut/test_exthereum$ mix deps.compile blockchain
==> blockchain
Compiling 17 files (.ex)

== Compilation error in file lib/blockchain/contract.ex ==

could not compile dependency :blockchain, "mix compile" failed. You can recompile this dependency with "mix deps.compile blockchain", update it with "mix deps.update blockchain" or clean it with "mix deps.clean blockchain"

The steps I took were:

1. mix new
2. add dependency ( [{:blockchain, "~> 0.1.5"}] )
3. mix deps.get
4. compile libsec... as in the README.md (I think it succeeded, after requiring me to install some missing debs)
5. mix compile in root dir

I'm on

Erlang/OTP 20 [erts-9.1] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false]

Interactive Elixir (1.5.1) - press Ctrl+C to exit (type h() ENTER for help)

Am I missing something?

Looks like we had a regression on 0.1.5 due to a dep incompatibility. Just pushed 0.1.6 which should fix your problem. Let me know if this works.

yep, compilation succeeds now, thanks!
