I think the best thing to do in your test would be something like:

  my $have_svscan = 0;

  if (find_svscan()) {
      $have_svscan = 1;
      plan tests => 2;
  }
  else {
      plan tests => 1;
  }

  use_ok("Proc::Daemontools");
  ok("Some svscan related test") if $have_svscan;

Where find_svscan looks in the Appropriate Places for svscan, and runs
the tests if it can be found.
