APE PLUGIN: http://sourceforge.net/projects/mac-port/
Both Should Be Installed ...
Mp3cue plugin: http://brianvictor.tripod.com/mp3cue.htm
Cueinfo Plugin: http://www.student.lu.se/~nbi98oli/xmms-cueinfo.html
Either is OK ...
Note: there is a small error of mac port, just delete the ";" at the end of line 9 in the file assembly.h
"Your.Path / Mac-3.99-U4 / SRC / maclib / askEMBLY / Assembly.h"
