ming simply doesnt work...

hi everyone!

as subject says, ming doesnt work on my server. i have tried compiling it a 
loooot of times and on few web server (and linux distros, too) - nothing helped.

last time i have tried to make it work was few days ago. i was recompiling php 
4.3.4 under gentoo linux. compilation went just fine, ming compiled with few 
warnings... 
when i execute this script (can be found under swftext function examples):

<?php
  $f = new SWFFont("_serif");
  $t = new SWFText();
  $t->setFont($f);
  $t->moveTo(200, 2400);
  $t->setColor(0xff, 0xff, 0);
  $t->setHeight(1200);
  $t->addString("PHP generates Flash with Ming!!");

  $m = new SWFMovie();
  $m->setDimension(5400, 3600);

  $m->add($t);

  header('Content-type: application/x-shockwave-flash');
  $m->output();
?>

all i get is

FWS}?ÒðÊ 
Cÿÿÿ 
_serif?¨ÓÀ? ?
ÿÿÿ ?»À]PHP generates Flash with 
Ming!!?
@ 

(i noticed that size of this junk depends of script itself)
when i execute "php <script_above.php>" from my shell, i get following error:

Fatal error: Cannot instantiate non-existent class:  swffont in 
/....../index.php on line 2

i have tried getting ming through CVS, but compilation fails.
any clues?!

btw, i was messing with cvs ming, and somewhere i have seen that there are some 
functions that should enable action sounds (eg. button clicks hovers etc. with 
custom sound) -- is that true?

pls help!!
