Configuring with:
./configure --host=none

Kinda hard to see... sorry..
	the static lib builds correctly.  the shared lib borks.. i ran into 
this same problem a few months back.. The same results with gcc 2.95.2 
and 3.1 included with OSX 10.2.3.  I did get the shared lib workin back 
then.. but alas, forgot how i did it.. I would play with it again, but 
have a test in the mornin.  There was a performance hit with the shared 
lib.. mostally because of PIC i believe.  I have to build with 
--host=none, because the assembly format changed.  I re-wrote a few of 
the altivec routines from assembly to C a few months back.. but i never 
really tested em.  If there is intrest, i can look at the code again 
and try to get them into a submittable form.  There has been some 
possibly useful altivec stuff happening on the ffmpeg side.  Might be 
worth lookin into..

dust.. aka  ptkme..
