compile sox for intel mac with .amr file support

compile a working binary of sox for the mac that includes support for AMR-WB and AMR-NB codecs. details at [login to view URL] sox supports .amr file playback with "optional" libraries that are not included in the default binary. specifically, sox supports "AMR-WB & AMR-NB (with optional libamrwb & libamrnb libraries)" again, just looking for this one extra features to be added to the mac version of sox. I'm running OS X leopard if it matters.
