Well I have dug at this for ever. Trying to get V5 to work with BTCZ. I have it connecting but giving an error on the pool and then rejecting all shares found. Yet it is mining just fine.
the command line and info is this:
  
# EWBF ZEC Miner version
EWBF_VERSION="3_4" # choose 3_3  or  3_4

# EWBF ZEC Miner optional arguments. add "--api $IPW:42000" if you want web info
EWBF_OPTS="--server mine-btcz-na.equipool.1ds.us --port 50062 --usr t1SgCLpJVGvVg5C8K7pfExw15MYE4RSRj5t.ti5000 --pass minpayout=.002 --algo 144_5 --pers BitcoinZ"

I have actually copied V5 into 3_4's dir so as not to have problems getting it to find 5.  I am on UBU 16.04

I mine ETH mostly but have to find other when they go POS.   Any ideas?
