What you can do (warning: this wiil disable host sanity checking, so
do this only if you know for sure, that yuo are connecting to right
host).

1) add line
StrictHostKeyChecking no to ~/.ssh/ssh_config
2) 
  $ rm ~/.ssh/known_hosts
  $ ln -s /dev/null ~/.ssh/known_hosts

This way your local host ignores the fact that there's is no line in
known_hosts corresponding to remote machine, gives you a warning about
adding new line and adds new line to /dev/null.

Tested. Proved to work.
