PHP library path?

Hi Experts,

My PHP skills are lacking, and I recently downloaded and installed an OpenSource PHP program on a shared Linux webhosting account, but I got an error message when I browsed to the site:
  'MDB2 Library not found on the server.  See the readme file for how to work around this'

So, I followed the instructions in the readme file, which were basically to run these commands from the command line:
    pear install MDB2
    pear install MDB2_Driver_mysql

I ran those, and attached is a log of the installs.  I still got the same error from the browser.

I saw that the MDB2 etc files were installed into the php directory in my home directory (i.e. /home/my-account/php), but I guess PHP doesn't know to look there, so how can I tell it to?  (In Perl I'd do something like: 'use lib "/home/my-account/perl5/..."').

I ended up working around this by putting the MDB2 etc files into the directory of the application, but I'd like to know the proper way of dealing with this.

Here's the code which generated the error message (it's in include/init.php):
    // Set up the DB
    if (!@include_once('MDB2.php')) {
      trigger_error('MDB2 Library not found on the server.  See the readme file for how to work around this');
      exit();
    }

I do not have root access to this shared server, just command line access.

Thanks.
