I don't understand why this isn't working. Change the $@ line to:

    ( $@ ) ? (print $done="false") : (print $done="true");

and see what you get.

Btw, one would more normally code the ?: expression as:

    $done = $@ ? "false" : "true";

Indeed, I would probably code the loop without use of while:

    { eval {
            # do stuff
        } or redo }
