Aha. Well, this is some problem with either the dba_ support or the dbm
support; you see, the dbm* functions are deprecated in PHP4.0 in favor of
the dba_* functions, which are a more generic interface. This has caused
us a lot of install problems.

Did you try setting your database type to "dbm" and see if that works? If
not, the next step is to set it to "dba" again, and edit dbalib.php and
remove the '@' symbol from the dba_open() call:

   function OpenDataBase($dbname) {
      global $WikiDB; // hash of all the DBM file names

      reset($WikiDB);
      while (list($key, $file) = each($WikiDB)) {
         while (($dbi[$key] = @dba_open($file, "c", "gdbm")) < 1) {

------------------------------^ right here

            $numattempts++;
            if ($numattempts > MAX_DBM_ATTEMPTS) {
               ExitWiki("Cannot open database '$key' : '$file', giving
up.");
            }
            sleep(1);
         }
      }
      return $dbi;
   }

With the '@' removed you will get a verbose error message telling us what
the problem is.
