[Qgis-user] SAGA-GIS on OS X 10.7

[William Kyngesburye]

I tested the Mac tests before committing them, though only as a bundled saga.  The second part is right, since the sagaPath() does not end with a '/'.  I was just being inconsistent in the use or not of os.path.join().

Try testing saga in a Terminal.  The test sextante uses is

saga_cmd shapes_points 16 /path/to/qgis/src/python/plugins/sextante/tests/points.shp ~/Desktop/polygons.shp

It should create the polygons.shp on your desktop.
