Then if upgraded bitcoin/d to 0.7 you NEED update p2pool

just upgraded to bitcoind 0.7 and latest p2pool from git.
im a little bit confused because i expected p2pool v5.
in fact it is 4.0-2-g11b0508
Odd, my node still sayin "5.0", git pulled today.
Anyway, complied last p2pool commit on win32 including LTC this time (finally get mingw working)

Will compile win64 version later today.
