I was having problems with some sextante algorithms in my QGIS 1.8, something related with wrong "os" name, I found a post in which reccomend to install the 1.9 master version.
I clean uninstalled the QGIS and then I installed the 1.9 version. When I activate the sextante toolbar, the Grass, TauDEM and even the QGIS algorithms doesn't appear in it. I have tried activating them in the configuration of sextante, reinstalling the plugin but the tools still missing.
Any ideas of what is happening?
