Thanks froodocooper

What I see is veqtrus Patch is applied in line 58 of the .\p2pool-master\p2pool\bitcoin\helper.py

Code should read:
         
    work['transactions'] = [x for x in work['transactions'] if x['txid'] == x['hash']] # don't mine segwit txs for now

so check if that is in your code...

If not add it ... and see if that works before trying for a rebuild ... cause that is what I am doing ...
