“dependencies”: {
“bignum”: “0.12.5”,
“async”: “1.5.2”,
“redis”: “0.12.1”,
“cli-color”: “1.1.0”,
“dateformat”: “1.0.12”,
“base58-native”: “0.1.4”,
“multi-hashing”: “git://”,
“cryptonote-util”: “git://”

I guess the problem is with correct cryptonote-util while building the pool from sources. What is the correct cryptonote-util after hard fork?

Pls see for reference official pool code
