There are no mp3 encoders in the official distribution probably because
of legal issues. You can download lame from
ftp://lame.sourceforge.net/pub/lame/src/
but it does not appear to be prepared to build debian packages.
Compilation should be easy.
If you don't care about mp3 (what's abcde?) you can use the vorbis beta3
packages in potato, save some work and get at least the same sound
quality and a free format. Or you can download the vorbis beta4 packages
from www.vorbis.com and get even better sound quality.
There was a thread about this recently on this list.
