The dba_ functions are an interface to several of the dbm-style database
libraries.  'Gdbm' is only one of the types of databases possible --- others
include 'dbm', 'ndbm', 'db2', db3'.  Which ones are available in your
PHP are determined at PHP compile-time.

To see which ones are supported in your php, create a file within
your web document tree called, say, 'info.php' containing one line:

<?php phpinfo(); ?> 

Then browse this file with your browser, you'll get a big page full
of all kinds of information about the configuration of your PHP.

A ways down that page there should be a table labeled 'dba'.  It should
look something like:

DBA support          |   enabled
Supported Handlers   |   gdbm db2 db3

(Except, I suspect in your case gdbm won't be listed as a supported handler.)

Pick one of the handlers which is supported --- I'm not completely up to
snuff on the differences between them all, but my guess is to prefer, in
this order: gdbm, db2, db3, ndbm, dbm.

Change line 39 in dbalib.php from
         while (($dbi[$key] = @dba_open($file, "c", "gdbm")) < 1) {
to
         while (($dbi[$key] = dba_open($file, "c", "db2")) < 1) {

I.e. change the "gdbm" to "db2" (or whatever dba handler your PHP supports.)

I think that should work.  (I've just tested it with 'db2' and that seems
to work fine.)

Note to maintainers: We should look into this a bit more.  Also make the
code auto-detect which handlers are supported.
