alpha build of avifile.

Hi,
	please see  
http://bento.freebsd.org/errorlogs/alpha-5-latest/avifile 
-0.7.38_2,2.log
it seems avifile 0.7.38 is missing 4 files, when I look at cvs  
(http://cvs.sourceforge.net/viewcvs.py/avifile/avifile-0.6/ffmpeg/ 
libavcodec/alpha/) it has dsputil_alpha.c, motion_est_alpha.c,  
mpegvideo_alpha.c, and simple_idct_alpha.c

release 0.7.37 has these files also. are they just missing from the  
distfile of 0.7.38 or what is going on?

thanks,
	michael
