The compile option for AAC playback is actually --enable-libfaad.  For
it to work on Mac OS, libfaad would need to compile there and be
installed prior to compiling the frontend with --enable-libfaad.  No
idea if libfaad will compile on OS X, or if the sniperpad guy does so.
 You could compile yourself and attempt to do so.
