Comment (by nieder):
(Mostly) False alarm.
The Xcode update is not the cause, it just happened right before the
failures started and I figured it would be the most likely cause. Found
the problem thanks to your md5/md5sum hint.
dpkg was updated on this machine at around the same time, and the newer
dpkg we are using in Fink no longer carries md5sum. Because md5sum is
still used for some things, we have a wrapper replacing it, but it uses
/sbin/md5 behind the scenes. If I modify ffmpeg/tests/md5.sh to search
for /sbin/md5 first, then the tests pass. Clearly the wrapper is not 100%
equivalent to the binary md5sum (our maintainer has been informed).
So if anything, maybe the search order logic in md5.sh might need to be
modified, but otherwise this isn't really a bug in FFmpeg. Sorry about
the noise.
