mrsid and ecw are not working on gvSIG 1.9 3D so you can skip them for the time being. I will be great if you can
compile them for the mac. Nevertheless the working mac version [1] seems to be using gdalframeworks and there are gdal
plugins for both ecw and mrsid [2]. 
Keep in mind that there are redundant libraries when installing sextante 0.5 in gvSIG+3D-1_9_0-1253mac-macosx-i586.
