Check which version of FFMpeg you have installed.
Currently supported versions are 0.5 through 0.8. http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#linff

If you don’t have a supported version of FFMpeg, the easiest workaround is to build Audacity without FFMpeg support.

The following commands should reset the configuration and build without FFMpeg support:

make distclean
./configure --without-ffmpeg 
make

The down side of building without FFMpeg is that you lose support for proprietary file formats that are supported by FFMpeg, such as WMA, AAC, and so on.

Use the ffmpeg-comat includes in src/FFmpeg.h

#include <ffmpeg-compat/libavcodec/avcodec.h>
#include <ffmpeg-compat/libavformat/avformat.h>
#include <ffmpeg-compat/libavutil/fifo.h>
#include <ffmpeg-compat/libavutil/mathematics.h>

I just added them before the others and it compiled for me.

Which Linux distro?
Did you need to install ffmpeg-compat-devel separately or was it already installed on your machine?

I’ve not found much documentation about ffmpeg-compat. Is that the “correct” way to use FFmpeg-compat or is it a “hack”?
