I just tried with current svn, and I do not get this error.

I do not get this error... I just checked, and compression_level is a
valid option (see libavcodec/utils.c). I see that you are using shared
libraries... Maybe ffmpeg_g ended up loading the wrong .so files (maybe
you have an older version installed somewhere)?

Looks like the used version of ffmpeg does not implement flac encoding
(it really looks like an old version).
Can you try to check that you are really using the correct libraries?
(try "ldd ffmpeg" to see which libraries are used, and then use "objdump
--dynamic-syms to check if flac_encoder is present)
