What steps will reproduce the problem?
1. Download the source for version 3.
2. Install flex, bison, and libavformat-dev. The latter isn't mentioned in the 
readme but seems to be required for the new AGG.
3. make

What is the expected output? What do you see instead?

The linker output is:

objs/ffCanvas.o: In function `ffCanvas::Impl::Impl(char const*, 
aggCanvas::PixelFormat, int, int, int, char*, int)':
ffCanvas.cpp:(.text+0x90): undefined reference to 
`avformat_alloc_output_context2'

What version of the product are you using? On what operating system?

Latest code from mercurial. Ubuntu 12.04. libavformat53 version 
4:0.8.3-0ubuntu0.12.04.1

More a documentation problem - README.txt should at least include

"Check out src-ffmpeg/README.ffmpeg for building ffmpeg or disabling ffmpeg 
support"

README.ffmpeg has been moved to the top level and the suggested reference has 
been added to README.txt

Confirmed on Ubuntu 12.04 64-bit for both the current dev version and the 3.0 
release that's currently on the Downloads page. Same error message.

I had just successfully compiled the 3.0beta4 version a couple weeks ago, and 
I've just confirmed that that version still compiles properly by checking out 
that version from mercurial ('hg clone -r Version3beta4_3 
https://code.google.com/p/context-free/ CF3').
