OK did some reading, got a copy of minerd and placed it in the /usr/bin folder. Got this output:
minerd -a neoscrypt -s 1 -o stratum+tcp://cryptopool.nl:3337 -O usr password -t 8 -r -1 -P
Miner started. You might not see any output for a few minutes.
dyld: Library not loaded: /opt/local/lib/libidn.11.dylib
Reference from: .usr/bin/minerd
Reason: image not found
Miner exited.
--EDIT
Got a new version of minerd, now I get the error"miner unknown algorithm"..
