= instead of eq (string comparison), and in any case even
using the wrong operator you'd have wanted == (equality
test) instead of = (assignment operator).

Just to start a formatting flamefest ;) I would have written 
this like this:

if ($ENV{'HTTP_REFERER'} eq "") {
  $previous = "an unknown site";
} else {
  $previous = $ENV{'HTTP_REFERER'};
}
