Now that I understand how Saga is used in Sextante, and how Saga in installed, I think Saga could be bundled with QGIS.  The saga_cmd would be in the app package bin/ where it would be found automatically by QGIS, and the libraries in lib/.

I could try an easy test outside of sextante/qgis by renaming my saga install folder and trying to run a simple command.

Well, the OS X build wiki page says you can package it as an app, which makes sense, though it's not part of the standard make install.  The saga_gui program is what gets launched in that case.
