I just updated curl with Macports and then I could make it but now can't connect to pool:
Stratum connection failed: Failed to connect to wood.suprnova.cc port 1158: Connection refused
./minerd -a skein -t 6 -s 4 -o stratum+tcp://wood.suprnova.cc:1158 -u Weblogin.WorkerName -p WorkerPassword
Suprnova's WoodCoin Pool // Algo: DoubleSkein // OFFLINE !
Sorry I'm only mining orphans, something is wrong with the code, i have no idea what as the wallet is also not giving out any kind of error etc. Pool will stay closed therefore.
