That's part of what the instructions cover - installing the autotools.

Anyways, I've been working on a packaging plan for saga within qgis.  I just got to the point of testing it, and it looks like Sextante does not care if the saga tools are in the current PATH (ie the QGIS bin folder), it requires a saga path to be configured in Sextante.  Problem is, there is a saga path option in the code, but there is no way to configure it in the Sextante preferences dialog box.  Orfeo and GRASS both have the preferences to set their paths, so this must be an oversight.

It says that the sysroot specified is added to all search paths, but I think it really means all search paths that are within the scope of the SDK.  /Library is not.  But /usr is, so it would still catch /usr/local, so the wx libraries would be a problem...
