It can't find the label because it's not in the same scope when the callback is invoked. A more effective solution would be to use an eval BLOCK e.g 
{
  alarm 2;
  ## don't set this globally!
  local $SIG{ALRM} = sub { die "timed out" };
  eval { callfc() };
  ## continue to next iteration if timed out
  next if $@ and $@ =~ /^timed out$/;
}
