Hello Guillaume,

	I forgot to check /usr/local/lib/ for previous development cruft.  i 
had an old copy of the libxvidcore quietly sleeping in there.  /me 
smacks himself..  I'm very sorry for the false alarm.

But on a different note.. building on linux ppc, without debugging (the 
-g flag) causes a segfault on encoding.  It occurs in a call to 
idct_int32.  When debugging is turned on with -g, everything seems to 
work fine..  the same occurs with both a static lib and a dyn lib.

I'll look into this more over the weekend.
