Thanks for the feedback that I got. I'm sorry if I didn't include
enough information the first time. Here is more info:

We have a server that we lease from Rackspace, a linux box running Red
Hat Enterprise Linux 3. Yesterday we tried to get some e-commerce
software going and we realized our build of PHP didn't have mhash
installed. So we called Rackspace and asked them to rebuild our copy of
PHP, this time including mhash. Rackspace did so. And then all of our
WordPress blogs died.

If you go here, you'll see that our WordPress blog is dead:

http://www.monkeyclaus.org/

also on the same server:

http://www.bluewallllc.com/blog/

All you'll see is what I'm echoing to the screen.

It turns out WordPress is now dying on this line:

$this->col_info[$i] = mysql_fetch_field($this->result);

That line is in wp-db.php (which is in the wp-includes folder).

Other sites on our server, including PHP/MySql sites, are having no
problem:

accumulist.com/

We're currently running version 4.3.2 of PHP.

The configure command for the new build of PHP was this:

'./configure' '--host=i686-redhat-linux-gnu'
'--build=i686-redhat-linux-gnu' '--target=i386-redhat-linux-gnu'

'--enable-shmop' '--enable-versioning' '--enable-calendar'
'--enable-dbx' '--enable-dio' '--enable-mcal'
'--with-apxs2filter=/usr/sbin/apxs'

Does anyone see anything missing? I assume that
'--with-mysql=shared,/usr' covers all the MySql stuff.

Any ideas?
