[Qgis-developer] SAGA modules (version 2.1.0) through SEXTANTE on Mac OSX

[Victor Olaya]

There is actually the following check in the case of mac and linux:

            command = ["saga_cmd"]
            proc = subprocess.Popen(command, shell=True,
stdout=subprocess.PIPE,
stdin=subprocess.PIPE,stderr=subprocess.STDOUT,
universal_newlines=True).stdout
            for line in iter(proc.readline, ""):
                if "________" in line:
                    settings.setValue(SAGA_INSTALLED, True)
                    return
            return "It seems that SAGA is not correctly installed in
your system.\nPlease install it before running SAGA algorithms."

basically, it is a naive check to see if executing saga_cmd in a
console returns something that looks like the SAGA CMD header. It
works fin in linux, but it seems it is not working in Mac. Are you
sure saga is in your path? if so, what do you see when you execute
saga_cmd? maybe the header is different for some reason?

Thanks in advance!
