build.rs fails to compile -> ethers-rs has made ethers::solc a feature rather than default

[plotchy]

This pr for ethers-rs has made ethers-solc an optional feature:
gakonst/ethers-rs#1463

build.rs depends on ethers::solc

[build-dependencies]
ethers = { git = "https://github.com/gakonst/ethers-rs" , features = ["ethers-solc"]}

After making the change, build.rs still fails to compile. I'm not familiar with the logic in that file, otherwise I would've made the fix a PR. Hope this helps.

Sorry, this repo could use some love. It's stuck in between experimental and usable.

#4 should solve your problem.
