Running Ubuntu 11.04 64 bit with CGminer 2.7.5 

when I try to mine litecoins and the pools is either PPS or P2POOL it doesn't matter (bitcoins no problem)... the miner says it is submitting shares and they are accepted but nothing seems to be received by either my PPS pool or my p2pool node.  ON my second box running win 7 I can scrypt mine just fine ... anyone have any ideas ?  thought about upgrading cgminer but on the version before 2.7.5 it wouldn't submit either.
