’sudo_update_prebinding’ press enterYou will have to wait a minute or so but you will get the promt back as below once again 
petes:~ petelaw$ just type ‘exit’ press enter and close the terminal application, then try your application again, they should work fine now, but you might need to restart you mac to finish the process.
