Did you notice any endless loop using --athlower ??

The fix is to do what Frank suggests: go to a data-encapsulted
type interface, where every parameter must be set via
a function. We would need to write about 100 functions
along the lines of: lame_set_input_samplerate().

So, you can either get rid of GNU emacs, or change it to use saner values.
To do the latter, you can stick the following in your .emacs file:
(defun linux-c-mode ()
"C mode with adjusted defaults for use with the Linux kernel."
(interactive)

LAME now has a ./configure script! It is from Florian Bomers.
It still needs work, since it's only been tested on two systems.
./configure ; make ; make install
should install lame, lame.h, libmp3lame.a and libmp3lame.so
in /usr/local/{bin,lib,include}
