For my framework-based Mac Qgis, GDAL is separate from Qgis.  My GDAL  
framework has separately downloadable plugins for the ECW and MrSID  
drivers, to avoid incompatible license problems.

Qgis has no problems reading ECW and MrSID when the GDAL plugins are  
installed, without rebuilding or repackaging Qgis.

Tom's all-in-one includes the GDAL library, so ECW and MrSID would  
have to be included in the Qgis package.
