Compile fails at ffmpeg

Slackware ver 14.0
Kernel version Linux version 3.2.29-smp

I'm wondering what version of ffmpeg this iteration of Audacity is built with. I installed the latest ffmpeg version from their git repository a couple of days ago.
It is version:
ffmpeg version N-45599-g9de5b11 Copyright (c) 2000-2012 the FFmpeg developers
built on Oct 16 2012 13:44:46 with gcc 4.5.2 (GCC)

Anyway when I try to build Audacity 2.0.3 I get the following errors:

In file included from AudacityApp.cpp:70:0:

Any Help greatly appreciated.

Audacity should support building against FFmpeg 0.5 through 0.8. It may not currently be possible to build Audacity against later versions of FFmpeg.
