[Qgis-developer] Shipping SAGA with QGIS

[Phil Hess]

>>Mac might be the biggest problem here. 

On Mac, SAGA should be distributed and installed as a normal OS X framework,
the way GDAL and PROJ are done. Mac users already download and install the
GDAL Complete.dmg package separately in order to run QGIS, so doing the same
with a SAGA.dmg package would not be a problem.

Currently you have to build SAGA 2.1.0 yourself to use it on Mac, so it's a
matter of someone creating the framework package and making it available
somewhere. It's also possible to create a package that installs saga_cmd and
the SAGA libraries in the standard Unix locations (/usr/local/bin, etc.),
but the Mac way would be to place them in a framework instead.

I tried installing SEXTANTE just now on a Mac but it crashed with a missing
"psycopg2" error message. This is not a standard Python package on Mac.
Probably installing this psycopg2 would be a bigger issue than installing
SAGA. It looks as though there are two ways to do it: compile it from
terminal command line or install via fink or MacPorts - neither of these is
likely to be something a non-developer QGIS user would be comfortable doing.

Thanks.
