Attention Mac users

Some people that set up a bukkit server on mac get an error code that says "failed to bind to port." This is easily fixable. Took me a while to finally understand how to do it but all you need to do is repaste the bin bash inside the text edit, make it plain text and save it as start. command. it has to have command otherwise it will not work. Anyway to fix the error you need to make sure that there is a space after chmod +x and you also need to make sure that your IP in server.properties is blank.
