osc library not working

hi guys,

i'm trying to control a rgb led on my arduino with my iphone. i got it working with processing but now i want to do it without my computer turned on. so i want to make it with a ethernet shield. now i try to use the recotana iosc library, but i got a lot of errors. the recotana site says i need arduino 14, downloaded it but it doesn't start up. can anybody help me with this. sorry for my bad english.
