This is old, please use current git head, see http://ffmpeg.org/download.html

You specified "--disable-everything" to disable the avi muxer, so it does not
work. I suggest you first try whatever you want to achieve with an
as-short-as-possible configure line (without --disable-everything and if
possible with static libraries), if it works, add --disable-everything and the
necessary --enable options (and use --enable-shared if necessary).
