 OK, lets try to first install ffmpeg properly and then those two
files may ffprobe just fine

 Well, it doesn't, but I was trying to disable all optimizations to
more easily debug my ffmpeg installation

$ ./configure --prefix=/media/sdc1/inst/sw/ffmpeg/ && make
yasm not found, use --disable-yasm for a crippled build

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

$ sudo dpkg --install /media/sdc1/_/sda1/prjx/ffmpeg/yasm_0.8.0-1_i386.deb

 then I tried again:

 but I don't see anything where the installation should have gone:
