Perhaps use the existing ssh-copy-id that comes with most of the *NIX ssh implementations?

Update: Aaah, I missed you're trying to put the key from box B onto box C run from A ( A =hop=> B =hop=> C). It'd be a cleaner thing to run than your cat | ssh cat >>... but it's still going to prompt for the remote password going to the third box C.

Second update: Never used it, but reading over the docs I think you want to do something like this with send rather than exec: 

## ... setup through to your login call the same
$ssh->send( qq{ssh-copy-id bkpuser\@10.11.12.13} );
$ssh->waitfor( qq{Password:} );
$ssh->send( $epass );
