Description:
------------
PHP is compiled as an Apache 1.3 DSO; 
./configure --with-apxs=/path/to/apxs 
            --with-gd 
            --with-zlib-dir=/path/to/dir

I just upgraded the PHP engine from 3.0.x to 4.3.4 and I'm debugging the php3 code.  According to http://php.net/imagepsloadfont, imagepsloadfont() is a built-in function, so I don't understand the Fatal Error.

Here is the line from my apache log:
[Wed Nov  5 18:33:04 2003] [error] PHP Fatal error:  Call to undefined function:  imagepsloadfont() in /path/to/chart.inc on line 322

Reproduce code:
---------------
Here is line 322 of chart.inc:
--------------------------------------
313 function render ($log = false, $cache = false)
    {
      if(!$this->is_chart)
        return false;
      $this->rescale();

      if ($log)
        $this->log = $log;

322   $fgc  = imagepsloadfont(_fontpath . "/type1/FGC_____.pfb");

      $im = imagecreate($this->x, $this->y);
      $bgcolor    = ImageColorAllocate($im, 255, 255, 255);
      $fgcolor[0] = ImageColorAllocate($im, 0, 0, 0);
      $fgcolor[1] = ImageColorAllocate($im, 0, 0, 255);
      $hicolor    = ImageColorAllocate($im, 255, 0, 0);
      $bdcolor    = ImageColorAllocate($im, 229, 227, 204);
330   $gridcolor  = ImageColorAllocate($im, 192, 192, 192);
---------------------------------

Also:

---------------------------------
15    define('_fontpath', '/path/to/fonts');
---------------------------------


Expected result:
----------------
I expect the code to make it through the engine without a Fatal Error.  The function is a built-in so I don't see how it would be undefined.

Actual result:
--------------
Here is the line from my apache log:
[Wed Nov  5 18:33:04 2003] [error] PHP Fatal error:  Call to undefined function:  imagepsloadfont() in /path/to/chart.inc on line 322
