I'm having a problem with the bitcore-lib fork found at: https://github.com/Groestlcoin/bitcore-lib

When I try to run "gulp test" I get the following error: Error: Cannot find module 'groestl-hash-js'

I'd make an issue on github but for some reason that repo doesn't allow you to make an issue...

It looks like the dependency wasn't added to the project correctly.
