PHP-GTK / PIMG / PHP-imagick Installation Issues

I am a PHP-GTK neophyte and not very experienced installing packages in Debian (Knoppix 3.3). I am trying to write a scriptable slideshow that will display images in two borderless X windows. PHP-GTK looks like a good place to start for someone more comfortable with PHP than C. PIMG also looks like it's worth a look, but I can't manage to get the imagick.so extension to work. It looks like the PHP -imagick Package was uses a different libmagick version. I'm running 5.5.7.9-1.1, which seems to be the latest version. Any helpful hints would be sincerely appreciated. Thanks! ** Error when running PIMG demo file pimg.php ** # ./pimg.php lwbeach.jpg Content-type: text/html PHP Warning: Unable to load dynamic library '/usr/lib/php4/20020429/imagick.so' - libMagick.so.6: cannot open shared object file: No such file or directory in Unknown on line 0 <br /> <b>Fatal error</b>: Call to undefined function: imagick_readimage() in <b>/root/pimg_12/pimg.php</b> on line <b>16</b><br />
